# LLM-guided program evolution improves 10 best-known circle-packing solutions (Packomania csqv, N=101-114) [R] > Source: > Published: 2026-09-09 17:00:33+00:00 I used an LLM to iteratively evolve an optimization algorithm rather than solve the packing directly. Starting from a simple seed solver, the LLM proposes algorithmic changes guided by a scoreboard of results and a history of prior attempts, and each candidate is scored by an independent verifier so
