Graph-GRPO: Stabilizing Multi-Agent Topology Learning via Group Relative Policy Optimization (2026.findings-acl)

Copied to clipboard

Challenge: Recent approaches to optimize communication topology rely on single-sample policy gradients with absolute rewards.
Approach: They propose a topology optimization framework that integrates Group Relative Policy Optimization.
Outcome: The proposed topology optimization framework outperforms state-of-the-art methods on reasoning and code generation benchmarks.
