Fork-and-Flush: A Basin-Hopping Trick to Stop AI Research Agents Fixating on One Idea
deliprao · x · 2026-10-13
Dimitris Papailiopoulos proposes Fork-and-Flush for AutoResearch: agents often develop tunnel vision toward one type of idea, like GD stuck in a local minimum. The fix: periodically fork the agent into T copies sharing the same workspace but with emptied context, let them run briefly, then continue from the best — essentially basin hopping for ideas. Commenters note the auto-research field is revisiting optimization's greatest hits: idea momentum, idea cross-entropy search, idea simulated annealing (related papers include DeltaEvolve, Contrastive Concept-Tree Search, and Idea Search).
