Summary

The Putnam Exam, an extremely challenging mathematics competition for undergraduates where the median score is typically zero, is explored as a benchmark for AI capabilities. A sample problem from the exam involves a game played by Alice and Bob with a string of 'n' numbers, each digit being 0, 1, or 2. Starting with all zeros, players take turns adding or subtracting one from a single digit to form a new string that has not appeared previously. The game ends when a player cannot make a valid move, and the other player wins. Alice always moves first, and the problem asks which player has a winning strategy, requiring intuition and pattern discovery.

Key takeaway

For AI researchers developing advanced problem-solving agents, evaluating performance against the Putnam Exam offers a robust measure of an AI's capacity for mathematical intuition and strategic discovery. Your models should aim to not just compute, but to identify underlying patterns and develop winning strategies in complex, combinatorial games, pushing beyond rote calculation.
