Co-evolving Agent Architectures and Interpretable Reasoning for Automated Optimization

Jiahao Huang, Peilan Xu, Wenjian Luo, Xiaoya Nan

Representing agent workflows as evolvable AOE-style networks and co-evolving their topologies with reasoning paths improves automated operations research performance and adds structural interpretability.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Empirical results on heterogeneous OR benchmarks show that the proposed framework consistently improves over zero-shot LLMs, fixed-pipeline OR agents, and representative evolutionary agent frameworks.

C2weakest assumption

That representing agent workflows as AOE-style networks and applying graph-mediated path-conditioned recombination plus multi-granularity semantic mutation will produce meaningful, generalizable improvements in complex OR reasoning and execution.

C3one line summary

EvoOR-Agent co-evolves agent architectures as AOE-style networks with graph-mediated recombination and knowledge-base-assisted mutation to outperform fixed LLM pipelines on OR benchmarks.
