Graph Neural Networks for Decentralized Multi-Agent Perimeter Defense

no code implementations23 Jan 2023 Elijah S. Lee, Lifeng Zhou, Alejandro Ribeiro, Vijay Kumar

In this work, we study the problem of decentralized multi-agent perimeter defense that asks for computing actions for defenders with local perceptions and communications to maximize the capture of intruders.
