StackPlanner: A Centralized Hierarchical Multi-Agent System with Task-Experience Memory Management
StackPlanner introduces a hierarchical multi-agent system that improves coordination among large language model-based agents through explicit memory management and reusable experience learning. The framework addresses critical limitations in centralized multi-agent architectures by decoupling high-level coordination from task execution and enabling agents to retain and leverage past coordination strategies, demonstrating improved performance on complex benchmarks.
