Primal-Dual based Safe Reinforcement Learning for Multi-Agent Navigation with Graph Information Aggregation

Description

This work presents a novel primal-dual based safe multi-agent reinforcement learning framework for multi-agent navigation tasks with graph information aggregation. The proposed method effectively addresses the challenges of ensuring safety and coordination among multiple agents in complex environments. By leveraging primal-dual optimization techniques, our method enables agents to learn optimal navigation policies while adhering to safety constraints. The integration of graph information aggregation allows agents to share and utilize information about their surroundings, enhancing their decision-making capabilities. Experimental results demonstrate the effectiveness of our method in achieving safe and efficient navigation in multi-UAV scenarios with different scales.
