By utilizing chatbots, artificial intelligence (AI) researchers have achieved a significant milestone in the field of mathematics. This innovative problem-solving method has opened up new opportunities for mathematical exploration and could revolutionize how we approach complex mathematical challenges.
Artificial intelligence researchers claim to have made the first-ever scientific discovery using a broad language model, marking a groundbreaking moment in the capabilities of chatbots such as Google’s Bard and OpenAI’s ChatGPT. This breakthrough suggests that these chatbots and similar software can offer insights that surpass human comprehension.
The breakthrough originated from Google DeepMind, where researchers sought to determine whether large language models (LLMs) powering chatbots could generate original insights rather than simply reusing existing training data. LLMs are powerful neural networks that use vast amounts of text and data to understand language patterns, including computer code.
Since its introduction, ChatGPT has generated a wide range of content, from vacation guides and academic essays to poetic works inspired by Shakespeare on the topic of climate change and troubleshooting broken software.
However, until now, chatbots were known for their inability to produce original information. They were susceptible to confabulation, which resulted in responses that were coherent and plausible but flawed, much like the ramblings of a skilled bar patron.
Pushmeet Kohli, the Head of AI for Science at DeepMind, expressed surprise at the project’s outcome, stating, When we started the project, there was no indication that it would produce something that’s genuinely new. He added, To the best of our knowledge, this is the first time a large language model has produced a true, novel scientific finding.
DeepMind introduced a system called FunSearch, which stands for searching in the function space. This system utilized an LLM to generate computer programs that addressed various challenges and paired them with an automatic evaluator, which assessed the performance of these programs. The top-performing programs were merged and fed back into the LLM, gradually improving the quality of the programs and enabling them to learn new information.
The researchers tested FunSearch on two mathematical puzzles. The first is the cap set problem, a well-known but relatively obscure topic in pure mathematics that involves determining the largest group of points in space whereby no three points lie on a straight line. FunSearch-generated programs produced new cap sets larger than any previously developed by mathematicians.
The second puzzle was the bin packing problem, which involves finding the most efficient way to pack containers with objects of various sizes. This concept is applicable to various scenarios, such as warehouse management and logistics. Traditionally, objects are packed into the first available bin or container with the least remaining space. However, FunSearch discovered a superior method that avoided leaving small gaps that were unlikely to ever be filled.
The publication of these results in the journal Nature has sparked further interest in the potential applications of FunSearch to other scientific problems. However, one significant limitation is that the problems must have answers that can be automatically verified, ruling out certain complex biological topics that often require lab testing.
While the immediate impact on scientists may be limited by these constraints, computer programmers stand to benefit from this innovation. Pushmeet Kohli believes that the gradual improvement of computer algorithms over the past 50 years, driven by human creativity, has significantly advanced coding practices. He stated, This will be transformative in how people approach algorithmic discovery and computer science.
Unlike the fear that AI might replace humans, LLMs are now being leveraged to push the boundaries of what algorithms can achieve while still requiring human intervention. Jordan Ellenberg, a mathematics professor at the University of Wisconsin-Madison and co-author of the paper, expressed excitement about the future of human-machine interaction in mathematics, stating, I find the prospects it suggests for the future of human-machine interaction in math really exciting, even more so than the specific results we found.
FunSearch creates programs that seek solutions rather than providing the solutions themselves. These programs can be read and understood by humans, potentially leading to new ideas and challenges in various fields.
The impact of this milestone achievement in mathematics and artificial intelligence raises profound possibilities for the future of scientific discovery and algorithmic innovation. As scholars continue to explore the capabilities of FunSearch and similar technologies, it is clear that AI has the potential to revolutionize the way we approach complex problem-solving in various disciplines.
