Parallel AI Agent Collaboration as Graph-Structured Distributed Block Optimization
Individually useful agent edits can damage a shared solution when merged; the paper gives a provable rule for retaining verified gains.
The method uses a known dependency graph to identify compatible edits, with improvements measured against the same current solution. Its merger preserves at least a 1/χ_f(G) share of total verified local improvement—a bound the authors prove tight for mergers selecting from the same proposals. Code-repair experiments show verified merging resolves conflicts that defeat naive merging. In twelve paired route-search runs, fractional scheduling cut measured wall time by a median of 15%, while route-cost changes varied across runs.
