Systematic evaluation finds no universally superior autonomous discovery harness; adaptive allocation outperforms fixed choices

A new arXiv preprint systematically decomposes OpenEvolve-style evolutionary search and TTT-Discover into constituent components, evaluating 30 budget-matched harnesses across 12 model-problem pairs using over 3.1 million LLM rollouts. Results show no fixed harness generalizes reliably across settings, and simpler alternatives often outperform OpenEvolve variants. The authors demonstrate that early discovery progress predicts final performance and use this to motivate an adaptive budget-allocation strategy that prunes weak runs and reallocates compute to stronger survivors, outperforming fixed harness selection.
