PROJECT EULER / SEMANTIC ATLAS

Question map

… questions UMAP / semantic space

A semantic atlas of mathematical problems

Find shape of
problem-solving.

Every dot is a Project Euler question. Neighbors share mathematical language and structure, not original number.

MAP MODEL

TeX-aware language encoder compresses each question to 32 semantic dimensions. Difficulty and time-normalized solving traction gently resolve close calls.
