Global Optimization for Combinatorial Geometry Problems Revisited in the Era of LLMs
arXiv:2601.05943v2 Announce Type: replace Abstract: Recent progress in LLM-driven algorithm discovery, exemplified by DeepMind's AlphaEvolve, has produced new best-known solutions for a range of hard geometric and combinatorial problems. This raises a natural question: to what extent can modern off-the-shelf global opt...
