Combinatorics is usually the most challenging and creative IMO problem category, particularly for AI systems.

“for four categories like algebra combinatorics geometry number theory usually combinatorics is kind of more the most challenging and creative especially for AI so like at one time I was at like this conference which is Frontiers Math Symposium so basically they invited like 30 to 40 mathematicians to kind of assess the capabilities of Alpha Mini High and many other advanced AIs.”
