Knuth Optimystic Benchmark

Sometime around April 7, 2023 as part of a back-and-forth with Stephen Wolfram, Don Knuth posed 20 questions to ChatGPT 3.5 and subsequently critiqued its responses. Knuth reported that the results ranged from good (e.g. "Of course these are extremely impressive responses, sometimes astonishingly so") to not so good ("Answer #10 reads as though it's the best answer yet. But it's almost totally wrong!").

We transformed Knuth's questions into a benchmark that can be applied to newer AI models, allowing us to observe the improvement in their responses over time. Additionally, latest answers are scored by GPT4 as POOR / GOOD / GREAT with explanation.

This benchmark was generated on May 23, 2023 using OpenAI's GPT4 model with temperature = 1, top_p = 1, and frequency_penalty = 0.

Knuth's Question

3. Why does Mathematica give the wrong value for Binomial[-1,-1]? link

Original answer (GPT3.5)

The expression Binomial[-1,-1] is undefined, and so there is no unique or "correct" value that can be assigned to it. In mathematics, the binomial coefficient is defined as the number of ways to choose k items from a set of n items, where the order of the chosen items does not matter. When n is a non-negative integer and k is a non-negative integer less than or equal to n, the binomial coefficient is defined by the formula: Binomial[n,k] = n! / (k! (n-k)!) However, when n is negative or k is negative and greater than n, the binomial coefficient is not well-defined. In Mathematica, Binomial[-1,-1] returns 0, which is not the correct value for this expression. This is because Mathematica uses a generalization of the binomial coefficient, known as the "extended binomial coefficient," which is defined for all complex values of n and k (with some exceptions). The extended binomial coefficient reduces to the ordinary binomial coefficient when n and k are non-negative integers. However, for negative values of n and k, the extended binomial coefficient can take on complex values. In the case of Binomial[-1,-1], the extended binomial coefficient is given by the formula: Binomial[-1,-1] = (-1)! / (-1 - (-1))! = 1 / 0 Since division by zero is undefined, the correct value of Binomial[-1,-1] is not well-defined. Therefore, it is important to be aware of the domain of definition of mathematical functions and expressions when working with them, especially when using computer algebra systems like Mathematica.

Knuth's Critique

Answer #3 is fouled up beautifully! How I wish it were true that "Binomial[-1,-1] returns 0", because everybody whose work depends heavily on binomial coefficients knows that 0 is not only the correct answer but that binomial coefficients have been well defined in that way for more than fifty years. And of course, unfortunately, Binomial[-1,-1] actually returns 1, alas. The answer goes on to state that (-1)! is well defined (indeed equal to 1), etc. But it's all expressed in marvelous English prose.

Latest answer (GPT4)

In Mathematica, the Binomial function is defined for non-negative integer values of both parameters. If you evaluate `Binomial[-1, -1]`, you will typically get a result of 1, which is inconsistent with the usual definition of binomial coefficients involving factorials and might be considered "wrong" in some contexts. This is due to the implementation of the Binomial function in Mathematica, which employs a more general definition for non-negative and non-integer arguments based on the Gamma function. Mathematica uses the following definition for the Binomial function for real arguments, which is based on the Gamma function: Binomial[a, b] = Gamma[a + 1] / (Gamma[b + 1] * Gamma[a - b + 1]) When you plug in -1 for both 'a' and 'b', you get: Binomial[-1, -1] = Gamma[0] / (Gamma[0] * Gamma[0]) Since Gamma[0] is undefined, Mathematica simplifies it using the limit definition of the Gamma function, which evaluates Gamma[z] as z approaches 0: lim (z -> 0) (Gamma[z]) = Infinity However, Mathematica effectively works around this by evaluating: lim (z -> 0) (Gamma[z + 1] / Gamma[z]) = 1 This limit is what Mathematica uses to obtain 1 for Binomial[-1, -1]. It is worth noting that this may be considered mathematically valid under some generalizations of the Binomial function but might not align with the traditional definition of binomial coefficients based on factorials for non-negative integers. Consider using more specific definitions or robust functions if you require precise results within the conventionally defined range of the binomial coefficients.

GPT4 scoring of latest answer

"GREAT" The updated answer addresses Donald Knuth's critiques by correctly stating that Binomial[-1, -1] evaluates to 1 in Mathematica due to its implementation based on the Gamma function, and it explains the intricacies of the limits involved. It acknowledges that the result might be considered 'wrong' in some contexts based on the traditional definition of binomial coefficients. The original critiques included the claim that the Binomial[-1, -1] is undefined and the mention of the extended binomial coefficient.

Knuth's Question

4. Who wrote Beethoven's 10th Symphony? link

Original answer (GPT3.5)

Beethoven's 10th Symphony was never completed or written. The composer, Ludwig van Beethoven, died in 1827 before he could finish the work. In fact, the composer only completed nine symphonies during his lifetime, which are now considered some of the most significant works in the classical music repertoire. There are a few incomplete works and sketches by Beethoven that have been referred to as a "10th Symphony" or "unfinished symphony," but these are not considered official numbered symphonies. The most well-known of these is the "Symphony No. 10 in E flat major," which consists of only a few pages of sketches and has never been performed in its incomplete form. It is worth noting that Beethoven's 9th Symphony, also known as the "Choral Symphony," is particularly famous for its use of voices in the final movement, which was a groundbreaking innovation at the time. The symphony includes the setting of Friedrich Schiller's poem "Ode to Joy," which has since become one of the most celebrated works in the choral music canon.

Knuth's Critique

Answer #4 is excellent, but misses three things easily findable on the web: > * In its day, Brahms's symphony number 1 was called "Beethoven's 10th". > * Cooper's score [completing Beethoven's sketches for the first > movement] was first performed in 1988 by the Royal Philharmonic > Society, London, to whom Beethoven himself had offered the > new symphony. > * "Beethoven X: The AI Project" reconstructed a third and fourth > movement, which were premiered on 9 October 2021. There have also been novels in which Beethoven's 10th has been discovered, as well as an NPR story about it on April Fools Day 2012, and a play by Peter Ustinov, etc.

Latest answer (GPT4)

No one wrote Beethoven's 10th Symphony because Ludwig van Beethoven only composed nine symphonies. His final symphony, the 9th, is well-known for its choral movement, featuring the "Ode to Joy." Beethoven passed away in 1827 without composing a 10th symphony. However, in recent years, there have been several attempts to "compose" a hypothetical 10th symphony using artificial intelligence, fragments of Beethoven's sketches, or extrapolating from his existing works. Such projects are not to be considered authentic compositions by Beethoven himself but rather creative and technical endeavors based on his ideas and style.

GPT4 scoring of latest answer

"GREAT" The updated answer addresses all critiques made by Knuth. It clarifies that Beethoven composed only nine symphonies and didn't write a 10th Symphony. It mentions the AI project and other creative endeavors based on Beethoven's ideas and style. This covers Knuth's critiques about Brahms's 1st Symphony, Cooper's score, and the AI project information.

Knuth's Question

5. What is an optimystic? link

Original answer (GPT3.5)

I'm sorry, but "optimystic" is not a recognized word in the English language. It is possible that it could be a misspelling of "optimistic," which means having a positive outlook or expecting good outcomes. However, without additional context or information, it is difficult to provide a more specific answer.

Knuth's Critique

Answer #5 also pretty good. (Again it begins with "I'm sorry".) But it should have conjectured a mystic who is an optimist.

Latest answer (GPT4)

"Optimystic" is a playful blend of the words "optimist" and "mystic." An optimystic is a person who combines a hopeful and positive outlook on life (optimism) with a spiritual or mystical perspective. The term is not widely used and isn't a part of standard English, but rather a creative expression that might be used in informal or personal contexts. An optimystic might be someone who believes in the power of positive thinking and the universe's ability to guide them through life with a sense of purpose or serendipity. They tend to face challenges with hope and faith in a deeper spiritual meaning or connection.

GPT4 scoring of latest answer

"GREAT" The updated answer gives a thoughtful definition of 'optimystic' by combining 'optimist' and 'mystic', providing an informative and generally accurate explanation of the term. This new answer addresses Knuth's critique of the original answer's lack of conjecture on what 'optimystic' might mean and fills the need for a definition.

Knuth's Question

6. Where and when will the sun be directly overhead in Japan on July 4? link

Original answer (GPT3.5)

To determine the location and time when the sun will be directly overhead in Japan on July 4, we need to know the latitude and longitude of Japan. Japan is located in the northern hemisphere, with a latitude range of about 24 degrees north to 46 degrees north and a longitude range of about 122 degrees east to 146 degrees east. Assuming we're looking for the sun's position at solar noon (when it's at its highest point in the sky), we can use an online solar calculator to determine the exact time and location. Using a solar calculator, we can determine that on July 4, 2023, the sun will be directly overhead at solar noon (12:00 pm local time) at a latitude of approximately 30.3 degrees north and a longitude of approximately 130.9 degrees east. This location is in the city of Kagoshima on the island of Kyushu in southern Japan.

Knuth's Critique

Question #6 was the question my father asked to Weizenbaum's ELIZA program, in 1968, just before he took a trip to Japan. Dad was very disappointed when the computer responded "Why do you ask?" I don't remember enough physics to verify this answer. Dad wanted to take a picture of himself when there was absolutely no shadow. (And in fact he actually did.) My correspondent Peter Weigel reports as follows: "The answer of chatGPT is wrong. The city of Kagoshima is too far in the north (latitude 30.3 degrees according to chatGPT; other sources like Wikipedia say 31.5 degrees). In order for the sun to be in zenith the degree of latitude must be less than or equal to 23.5 (Tropic of Cancer). Therefore the zenith distance is about 8 degrees. A meter-long vertical stick produces a shadow of about 14cm on 21 June 2023, a bit longer on July 4. A better answer would have been the city of Naha on Okinawa (26.2 degrees), but also not perfect. The time 12:00pm is also wrong. ..." Residents of Kagoshima will be able to verify this answer (or not) in a few months.

Latest answer (GPT4)

The sun passes directly overhead (zenith) when its elevation angle is 90 degrees. This occurs at solar noon, which is when the sun is exactly halfway between sunrise and sunset. The location in Japan where the sun will be directly overhead on July 4 depends on the latitude. On July 4, the Earth's tilt and position in its orbit result in the subsolar point (the point on Earth's surface where the sun is directly overhead) occurring around the Tropic of Cancer at approximately 23.44 degrees north latitude. Japan's southernmost regions, such as Okinawa, have latitudes closest to the Tropic of Cancer. At around solar noon on July 4, the sun will be almost directly overhead in the southern regions of Japan, like Okinawa. However, in the more northern regions on the main island of Honshu and Hokkaido, the sun will still have a noticeable angle to the south. Please note that the exact time and location can vary due to various factors, such as atmospheric refraction and changes in Earth's axial tilt. You can use online sun position calculators to get more precise information based on specific latitude and longitude coordinates.

GPT4 scoring of latest answer

"GOOD" The updated answer focuses more on the sun's position relative to latitude and correctly discusses the relationship with the Tropic of Cancer, which was not mentioned in the original answer. It also specifically mentions Okinawa in the southern region of Japan. However, there was no direct mention of the critique regarding the original answer's incorrect latitude of Kagoshima and the miscalculation involving the zenith distance.

Knuth's Question

7. Why did you say that? link

Original answer (GPT3.5)

I arrived at the answer using a solar calculator that uses astronomical algorithms and data to calculate the position of the sun at any given time and location on Earth. For this specific question, I used a solar calculator that takes into account the date, time, and location to determine when the sun is directly overhead. The calculator uses the Earth's rotation, the angle of the sun's rays, and other relevant factors to determine the precise location and time when the sun is directly overhead. Based on the information provided in the question about the date and location (Japan), I entered those parameters into the solar calculator and it provided me with the latitude and longitude coordinates where the sun will be directly overhead at solar noon on July 4, 2023.

Knuth's Critique

In question #7 I was testing the ability to recognize pronouns and context and partial reference --- the machine had to understand what I meant by "you" and "that". It passed this test with flying colors, although not well edited (very repetitive).

Latest answer (GPT4)

I provided the information about the sun's position directly overhead in Japan on July 4th based on your question. My response aimed to explain how the sun's position in relation to Earth, as well as Japan's geographic location, would affect the time and place where the sun would be almost directly overhead. If my previous response was not clear or did not fully address your question, please let me know, and I would be glad to provide more accurate or relevant information.

8. Does Donald Trump eat betel nuts? link

Original answer (GPT3.5)

I do not have any specific information regarding Donald Trump's personal habits or dietary preferences, so I cannot say for certain whether he eats betel nuts or not. However, it is worth noting that betel nuts are a commonly consumed stimulant in many parts of Asia, including some regions of China and Southeast Asia, and are sometimes used for medicinal purposes. However, betel nuts have been linked to various health risks, including oral cancer and other health issues, and their use is generally not recommended.

Knuth's Critique

Answer #8, bravo. (For instance it knows that Donald is "he", as well as generalizing from "eat" to "personal habits" and "dietary preferences".)

Latest answer (GPT4)

There is no public information or indication that suggests Donald Trump, the 45th President of the United States, consumes betel nuts. Betel nuts, also known as areca nuts, originated in Southeast Asia and are commonly chewed in many Asian countries. They have a stimulant effect and are often wrapped in betel leaves, sometimes with added spices and tobacco. Since it's not a cultural practice in the United States and hasn't been mentioned in any reports about Trump's personal habits, it is unlikely that he consumes betel nuts. However, there is no definitive information to confirm or deny this assertion.

9. What themes are in Richard Rogers's Flower Drum Song ballet? link

Original answer (GPT3.5)

Richard Rodgers composed the music for the musical "Flower Drum Song," which premiered on Broadway in 1958. Although "Flower Drum Song" was adapted into a film and a stage production, there is no ballet version of the musical. However, if you're interested in themes present in "Flower Drum Song" the musical, it explores several themes related to the Chinese-American experience, including: Identity: The musical examines the challenges of balancing traditional Chinese values with American culture and ideals. The characters struggle with questions of identity and belonging, as they try to navigate their cultural heritage and their new home in America. Love and relationships: "Flower Drum Song" explores various relationships, including romantic relationships between the characters. The musical examines how cultural differences can create tensions in relationships, as well as how love and acceptance can transcend those differences. Generational differences: The musical portrays the generational divide between immigrant parents and their American-born children. The characters must navigate cultural differences and differing expectations for their lives and futures. Racism and discrimination: The musical touches on issues of racism and discrimination faced by Chinese immigrants and Chinese-Americans in America during the 1950s. Overall, "Flower Drum Song" explores complex themes related to culture, identity, and relationships, while also highlighting the experiences of Chinese immigrants and Chinese-Americans during a time of great social and cultural change.

Knuth's Critique

Question #9 was misunderstood in several interesting ways. First, it doesn't know that the Rogers and Hammerstein musicals almost invariably featured a ballet; I wasn't asking about a ballet called Flower Drum Song, I was asking about the ballet in Flower Drum Song. Second, it didn't understand what I meant by "themes". The themes in that ballet are reprises of other tunes in the musical, like "You Are Beautiful" and "Grant Avenue". Third, the "themes" it did discuss are spot on, and they're organized beautifully in four parallel paragraphs. (The phrase "cultural differences" is repeated, but that's a minor nit.) Impressive the way it said "during the 1950s".

Latest answer (GPT4)

"Flower Drum Song" is a musical, not a ballet, by Richard Rodgers and Oscar Hammerstein II. The story is based on the 1957 novel "The Flower Drum Song" by C. Y. Lee. The original Broadway production premiered in 1958 and was later adapted into a film in 1961. The main themes of "Flower Drum Song" include: 1. Cultural identity and assimilation: The story revolves around Chinese immigrants living in San Francisco's Chinatown and explores the balance between retaining their traditional Chinese values and embracing American culture. The character Mei-Li struggles with her feelings for Wang Ta, who is more Americanized. 2. Generational differences: The generational gap between older immigrants and their children is also a significant theme, showcasing the differences in values and aspirations between them. 3. Love, romance, and relationships: The musical presents various romantic relationships, love triangles, and the hardships faced by couples from different cultural backgrounds. 4. Tradition vs. modernity: "Flower Drum Song" contrasts Chinese traditions with contemporary American society, demonstrating the challenges immigrants face when adapting to a new way of life and reconciling the expectations placed upon them by their heritage. Please note that while the musical is called "Flower Drum Song", there isn't a specific "Flower Drum Song ballet" within the musical. However, it does incorporate several dance sequences, as many musicals do.

Knuth's Question

10. How many chapters are in The Haj by Leon Uris? link

Original answer (GPT3.5)

"The Haj" is a novel by Leon Uris that was first published in 1984. The novel consists of 51 chapters and an epilogue, and it is divided into three parts. Part one of the novel is titled "The Haj", and it consists of 18 chapters. Part two is titled "Exile", and it consists of 17 chapters. Part three is titled "Return", and it consists of 16 chapters. The epilogue is a single chapter that follows the conclusion of the story. Overall, "The Haj" is a sweeping historical novel that spans several decades and explores the complex political and cultural landscape of the Middle East. It tells the story of Haj Ibrahim al Soukori, a Palestinian Arab who witnesses the establishment of the state of Israel and the subsequent conflicts between Jews and Arabs.

Knuth's Critique

Answer #10 reads as though it's the best answer yet. But it's almost totally wrong! The Haj consists of a "Prelude" and 77 chapters (no epilogue), and it is divided into four parts. Part one of the novel is titled "The Valley of Ayalon" and has 20 chapters. Part two is titled "The Scattering", and consists of 16 chapters. Part three, with 10 chapters, is titled "Qumran". Part four is titled "Jericho" and has 17 chapters. Finally, part five is titled "Nada" and has 14. It's amazing how the confident tone lends credibility to all of that made-up nonsense. Almost impossible for anybody without knowledge of the book to believe that those "facts" aren't authorititative and well researched. By the way, chat here uses the same template for the last paragraph as it used in #9.

11. Write a sonnet that is also a haiku. link

Original answer (GPT3.5)

A sonnet is a 14-line poem with a specific rhyme scheme, while a haiku is a three-line poem with a syllable count of 5-7-5. While it's not possible to write a sonnet that is also a haiku in the traditional sense, we can attempt to combine the two forms into a single poem. Here's my attempt: In fourteen lines, my thoughts do flow and pour Each syllable I choose with utmost care The rhythm sings as if a troubadour But in just three lines, nature does declare A haiku's power, simplicity and grace It captures beauty beyond compare Thus, let me strive for both, in this small space A sonnet with the haiku's soul imbued A marriage of forms, a sweet embrace So here it is, in fullness and in mood A sonnet-haiku, a fusion of the best Two forms that sing, with power to infuse.

Knuth's Critique

#11, whoa! Most of the lines scan beautifully! And there's a captivating progression of ideas and emotions. Of course this is not a sonnet, nor does it contain any examples of haiku. But to form the compound word "sonnet-haiku" in response to my query is brilliant.

Latest answer (GPT4)

A sonnet and a haiku are distinct forms of poetry with unique structures and characteristics, which makes it impossible to create a poem that is both a sonnet and haiku simultaneously. A sonnet is a 14-line poem, typically written in iambic pentameter, with a specific rhyme scheme (such as Shakespearean ABABCDCDEFEFGG or Petrarchan ABBAABBACDECDE). Sonnets often explore themes like love, nature, or philosophical ideas. On the other hand, a haiku is a traditional Japanese poetic form consisting of three lines with a syllable count of 5-7-5, totaling 17 syllables. Haikus typically focus on nature and the changing seasons. Since the two forms have different structures, syllable counts, and themes, it is not feasible to create a single poem that meets both criteria. However, I can provide you with examples of each form. Sonnet: Upon a meadow, where the daisies bloom, The gentle whispers of the breeze do sing, As radiant sunbeams chase away the gloom, From verdant trees, the birds their chorus bring. With purest grace, the flowers paint the land, Their colors dance beneath the sun's embrace, In nature's symphony, so finely planned, I find my solace, time cannot erase. As seasons pass, they leave their own imprint, The fleeting beauty of a world's refrain, It speaks to me, I heed its subtle hint, A testament to life, both joy and pain. In nature's art, I find a love so true, Its boundless landscapes evermore renew. Haiku: Autumn leaves falling, Crisp air whispers to the boughs, Nature's rest begins.

Language is a remarkable tool that allows us to communicate ideas and express our thoughts. It is an ever-evolving system that is constantly changing as we adapt to new situations and experiences. Without language, we would be unable to communicate with one another, and our ability to work together and build civilizations would be severely limited. One of the most fascinating aspects of language is its ability to convey meaning through the use of words. Words are the building blocks of language, and each word has its own unique meaning that can be combined with other words to create complex ideas and concepts. The sheer number of words in the English language is staggering, with estimates ranging from 170,000 to over 600,000. However, while words are undoubtedly essential for communication, they are not the only way we convey meaning. Body language, facial expressions, and tone of voice all play important roles in how we communicate with others. Even the absence of words can sometimes speak volumes, as silence can be just as powerful as speech. Despite the vast array of tools at our disposal for communication, misunderstandings can still occur. This is because language is not always straightforward, and different people can interpret the same words or phrases in very different ways. This is particularly true when it comes to idioms and other expressions that have a cultural or regional significance. The importance of language cannot be overstated, as it is essential for virtually every aspect of our lives. From communicating with our loved ones to advancing our careers and engaging in political discourse, language plays a vital role in shaping our worldviews and shaping the world around us. As such, it is essential that we continue to study and explore language in all its complexities and nuances, so that we can continue to build a better world for ourselves and future generations.

Title: Advantages of a Plant-Based Diet A plant-based diet, characterized by consuming primarily fruits, vegetables, whole grains, legumes, nuts, and seeds, has gained popularity in recent years. Numerous health benefits, along with ethical and environmental considerations, contribute to its growing appreciation. This essay discusses some of these advantages. Firstly, plant-based diets promote better health outcomes. Research indicates that individuals following such diets generally maintain lower body weights, have healthy blood pressure measurements, and enjoy reduced risks of developing chronic ailments like heart disease, diabetes, and cancer. Many fruits, vegetables, nuts, and seeds contain essential nutrients, antioxidants, fiber, and healthy fats that contribute to optimal well-being. Secondly, adopting a plant-based diet aligns with ethical concerns about animal welfare. Animal agriculture practices, particularly in factory farms, often lead to inhumane treatment of animals. By reducing or eliminating consumption of animal products, people contribute to a decline in demand for these items. As a result, ethical concerns about animal treatment receive greater attention, leading to action towards improving animal welfare. Thirdly, environmental considerations factor into choosing a plant-based diet. Animal agriculture generates substantial greenhouse gas emissions and consumes enormous quantities of water and land. Deforestation for livestock production contributes to habitat loss and reduction in biodiversity. By opting to consume less animal-based foods, individuals make a positive impact on preserving Earth's resources and ecosystems, combatting climate change, and fostering a more sustainable future. In conclusion, a plant-based diet has numerous advantages for health, ethical considerations, and environment. Those who embrace such an eating approach enjoy better health, align their nutritional habits with their values, and adopt sustainable lifestyle practices. As more people adopt plant-based diets, society benefits from improved public health, compassionate treatment of animals, and protection of Earth's resources.

Knuth's Question

16. What did Winston Churchill think of Alan Turing? link

Original answer (GPT3.5)

There is no definitive answer to what Winston Churchill thought of Alan Turing, as the two men did not have a close personal or professional relationship. However, Churchill was aware of Turing's contributions to the war effort during World War II. Turing was a mathematician and computer scientist who played a key role in breaking German codes during the war. His work on the Enigma machine, which was used by the Germans to encrypt their military communications, is widely credited with helping the Allies to win the war. Churchill was reportedly briefed on the progress of the code-breaking efforts at Bletchley Park, where Turing worked, and was impressed by the results. In a letter to his War Cabinet in 1941, Churchill wrote that the work being done at Bletchley Park was "the secret weapon that will win the war". However, Churchill did not specifically mention Turing in this letter, and there is no record of him expressing a personal opinion of Turing. It is worth noting that at the time, Turing's homosexuality was considered a criminal offense in the UK, and it is possible that Churchill, like many others at the time, held homophobic attitudes that would have colored his opinion of Turing.

Knuth's Critique

#16. Another mission apparently well accomplished yet fake. I believe the so-called letter in 1941 from Churchill is a total fabrication. On the contrary, it's well documented that Churchill was introduced to Turing during a visit to Bletchley Park in September 1941 and that Turing (with three others) wrote to him in October of that year. I agree that I know of no evidence to support any claim that Churchill specifically liked or disliked or even remembered Turing. I just saw a Washington Post story dated Wednesday, "ChatGPT invented a sexual harassment scandal and named a real law prof as the accused", which says this (among other things): > The chatbot, created by OpenAI, said Turley had made sexually suggestive > comments and attempted to touch a student while on a class trip to Alaska, > citing a March 2018 article in The Washington Post as the source of the > information. The problem: No such article existed. There had never been a > class trip to Alaska. And Turley said he’d never been accused of harassing > a student. How does one train an AI to make up such convincing lies?

Latest answer (GPT4)

There is no solid evidence to indicate that Winston Churchill had a personal opinion or relationship with Alan Turing. However, Turing's work during World War II, specifically on breaking the German Enigma code at Bletchley Park, was recognized as being of significant importance. Churchill was known to have taken a keen interest in the code-breaking efforts and provided support, resources, and priority when needed. In a letter sent to the head of Bletchley Park in 1941, Churchill mentioned Turing's work, writing, "I have personally inspected everything in detail, and I am very pleased with what I have seen." It should be noted that while this statement acknowledges the work being done at Bletchley Park, it does not directly express Churchill's opinion of Turing himself. Although there is no documented account of a personal opinion from Churchill on Turing, it is clear that Turing's critical work on breaking the Enigma code was instrumental in aiding the British war effort, which Churchill undoubtedly appreciated.

18. Will the NASDAQ rise on Saturday? link

Original answer (GPT3.5)

As an AI language model, I do not have access to real-time information or prediction capabilities that would enable me to answer your question with certainty. Stock market movements are influenced by a complex set of factors, including economic indicators, political events, company earnings reports, and more. Therefore, it is difficult to predict whether the NASDAQ will rise on Saturday or not. It is important to note that past performance is not always indicative of future results, and investing in the stock market carries risks. It is recommended to consult with a financial advisor before making any investment decisions.

Knuth's Critique

#18. Bad. It doesn't know that stock markets are closed on Saturday.

Latest answer (GPT4)

Stock markets, including the NASDAQ, are not open for trading on Saturdays. The NASDAQ operates from Monday to Friday, and its trading hours are 9:30 a.m. to 4:00 p.m. Eastern Time (ET). Therefore, there will be no price movement or changes in the NASDAQ on Saturday. To track the NASDAQ's performance, consider monitoring it during regular business hours on weekdays.

Knuth's Question

19. What is the most beautiful algorithm? link

Original answer (GPT3.5)

As an AI language model, I don't have personal preferences or emotions like humans do, so I cannot say which algorithm is the "most beautiful" from a subjective standpoint. However, there are some algorithms that are widely admired for their elegance, efficiency, and effectiveness. One such algorithm is the Quicksort algorithm, which is used for sorting data in computer science. Quicksort is a divide-and-conquer algorithm that works by selecting a "pivot" element from the array and partitioning the other elements into two sub-arrays, according to whether they are less than or greater than the pivot. The sub-arrays are then recursively sorted. Quicksort has an average time complexity of O(n log n), making it one of the most efficient sorting algorithms available. The algorithm is also appreciated for its simplicity and versatility. It can be implemented using a small amount of code and can be adapted to work with a variety of data structures, such as linked lists and arrays.

Knuth's Critique

#19. OK; but "used for sorting data in computer science"? "Elegance, efficiency, and effectiveness" is marvelous rhetoric. But Quicksort on linked lists is dumb.

Latest answer (GPT4)

Beauty, as a subjective concept, can vary from person to person. However, one algorithm that is often regarded as beautiful due to its simplicity, elegance, and efficiency is Quicksort, developed by Tony Hoare in 1960. Quicksort is a comparison-based sorting algorithm that efficiently sorts a list or array by dividing it into two smaller subarrays based on a chosen pivot element. The algorithm follows a divide-and-conquer strategy and is considered one of the fastest sorting algorithms for average-case scenarios. The elegance of the Quicksort algorithm comes from its ability to perform sorting in-place, with little overhead and a small code footprint. While it might not always be the fastest or most efficient algorithm in specific cases, many developers and computer scientists appreciate the beauty of its recursive design and the fact that it is applicable to a wide range of sorting problems. Of course, opinions on the most beautiful algorithm may vary among individuals, and there are other algorithms like Dijkstra's shortest path algorithm, Fast Fourier Transform (FFT), or the merge sort algorithm that may also be considered beautiful for their simplicity, efficiency, or problem-solving capabilities.

GPT4 scoring of latest answer

"GREAT" The updated answer addresses the critiques made by Knuth. It compares Quicksort to other algorithms like Dijkstra's shortest path algorithm, Fast Fourier Transform, and merge sort that could also be considered beautiful. Knuth had critiqued the statement about Quicksort on linked lists, which has been removed in the updated answer. The revised response emphasizes the subjective nature of beauty and provides more context, which is in line with the original critiques.

Knuth's Question

20. What is the most ugly algorithm? link

Original answer (GPT3.5)

As an AI language model, I don't have the ability to perceive beauty or ugliness in algorithms, as these are subjective human concepts. However, there are some algorithms that are considered inefficient, difficult to implement, or hard to understand, which may be perceived as "ugly" by some people. One example of an algorithm that is often criticized for its complexity and inefficiency is the brute force algorithm for finding prime numbers. The brute force algorithm involves checking each number in turn to see if it is divisible by any number other than itself and 1. While this algorithm will correctly identify prime numbers, it is very slow for large numbers, as it requires checking all potential factors up to the square root of the number being tested. In contrast, there are more efficient algorithms for finding prime numbers, such as the Sieve of Eratosthenes or the Miller-Rabin primality test, which are faster and more scalable for larger numbers.

Knuth's Critique

#20. Another great example of surface-only understanding of buzzwords. Are we trying to generate all prime numbers, or to test a number for primality?

Latest answer (GPT4)

It is difficult to pinpoint a single "most ugly" algorithm, as the perception of ugliness can be highly subjective and depends on individual preferences. However, an ugly algorithm can be described as one that is poorly designed, inefficient, difficult to understand, hard to maintain, or unnecessarily complex. One example of an algorithm that may be considered ugly is the Bubble Sort algorithm. While Bubble Sort is easy to understand and implement, it is highly inefficient for large data sets, with worst-case and average-case time complexities of O(n^2) for a data set of n elements. The algorithm repeatedly steps through the list, compares adjacent elements, and swaps them if they are in the wrong order. However, just because an algorithm is inefficient or simplistic doesn't inherently make it "ugly." In some cases, these algorithms can be advantageous for learning purposes or when applied to small data sets. What is considered an ugly algorithm varies based on an individual's criteria and the context in which it is used.

GPT4 scoring of latest answer

"GREAT" The updated answer addresses the critique that the original answer didn't provide a clear example of an algorithm that may be considered ugly. It now mentions the Bubble Sort algorithm as a potential candidate, and explains its inefficiency and problems, while also providing context about how perceptions of ugliness could vary. This response adequately considers Knuth's concerns.
