Optiver has posted a series of math puzzles. Their process is to first make an educated guess using a heuristic and then working through the math. Ideally, the heuristic will be very simple and quick, but still relatively accurate.
The puzzles were also given to Claude to compare answers. These questions are an excellent test for AI in general. In some cases Python dashboards are useful for visualization. Claude is also asked what it thinks the question is meant to illustrate.
