Topological Coherence for Self-evolving Multi-agent Systems

Complex tasks inherently couple workflow structure, agent responsibility, collaboration, and memory access: task regions delimit responsibility and tool scope, cross-region dependencies give rise to handoffs, and ownership boundaries delimit private and selectively shared memory. Existing methods can jointly optimize a...

CoMemBench: Benchmarking Collaborative Memory Boundaries across Multi-Agent Workflow Topologies

CoMemBench is introduced, an execution-grounded benchmark for collaborative memory sharing and isolation across multi-agent workflow topologies, and reveals a sharing-isolation trade-off: broader context improves information availability but can weaken isolation, while system rankings shift across topologies and artifa...
