Automating mathematical reasoning has been a long-standing goal of artificial intelligence, and formal frameworks such as Lean 4, Isabelle, and Coq play an important role. These frameworks allow users to write machine-verifiable proofs of mathematical theorems, providing a structured environment for proving complex problems. The development of neural theorem provers, which aim to automate this process, requires rigorous benchmarks to evaluate their effectiveness and drive further research.
A critical issue in ai-powered theorem proving is the lack of comprehensive benchmarks that challenge these systems with advanced mathematical problems. Existing benchmarks, such as MINI F2F and FIMO, focus primarily on high school-level mathematics and need to sufficiently test the capabilities of neural theorem provers on more complex university-level problems. This gap requires the creation of a more robust benchmark that encompasses a broader range of mathematical challenges.
UT Austin researchers have presented Putnambench (Putnambench)a new benchmark designed to evaluate neural theorem provers using problems from the William Lowell Putnam Mathematical Competition. This competition is renowned in North America for its challenging college-level mathematics problems, making it an ideal source for a rigorous benchmark. PUTNAMBENCH includes 1697 formalizations of 640 problems, each available in Lean 4 and Isabelle and a significant subset in Coq. This multilingual approach ensures comprehensive assessment in different theorem proving environments.
The PUTNAMBENCH methodology involves manually constructing formalizations of Putnam's proficiency problems, ensuring that each problem is carefully debugged and available in multiple formal proof languages. These formalizations cover various topics taught in undergraduate mathematics courses, such as algebra, analysis, number theory, and combinatorics. The problems are designed to test significant problem-solving skills and proficiency in various mathematical concepts, making PUTNAMBENCH a challenging benchmark for neural theorem provers.
The evaluation of PUTNAMBENCH used several neural and symbolic theorem provers, including Draft-Sketch-Prove, COPRA, GPT-4, Sledgehammer, and Coqhammer. These methods were tested on all 1,697 formalizations, with each technique attempting to solve the problems using its unique approaches. The results showed that the current methods could only solve a handful of the PUTNAMBENCH problems. For example, GPT-4 solved only one of the 640 problems in Lean 4 and Coq, while Sledgehammer solved three of the 640 problems in Isabelle.
One of the key challenges highlighted by the PUTNAMBENCH evaluations is the difficulty of synthesizing new lemmas and orchestrating them into complex proofs. While current theorem provers can effectively stitch together standard proof steps well represented in their training corpus, they often need help creating new and innovative proof strategies. This limitation underscores the need for more advanced neural models that can leverage deep mathematical knowledge and reasoning.
The multilingual nature of PUTNAMBENCH sets it apart from previous benchmarks. By including problems from Lean 4, Isabelle, and Coq, PUTNAMBENCH allows for a more comprehensive evaluation of theorem proving methods. This approach ensures that the benchmark can test the robustness of theorem provers in different formal proof environments, providing a complete picture of their capabilities and limitations.
In conclusion, PUTNAMBENCH, by providing a diverse set of 1697 Putnam competition problem formalizations in multiple formal proof languages, addresses the limitations of existing benchmarks and sets a new standard for rigor and comprehensiveness. The results of the current evaluations indicate that while progress has been made, there is still a long way to go in developing neural theorem provers capable of solving complex mathematical problems. PUTNAMBENCH will undoubtedly be crucial in driving future research and innovation.
