Multi-Agent Lipschitz Bandits

arXiv:2602.16965v2 Announce Type: replace Abstract: We study the decentralized multi-player stochastic bandit problem over a continuous, Lipschitz-structured action space where hard collisions yield zero reward. Our objective is to design a communication-free policy that maximizes collective reward, while separating coordination costs from learning costs. We propose a modular protocol that first solves the multi-agent coordination problem by identifying and seating players on distinct, high-value regions via a novel maxima-directed search and then decouples the problem into $N$ independent sin

Why this matters
Why now

The increasing complexity and scale of multi-agent AI systems, particularly in decentralized settings, necessitate robust coordination and learning mechanisms to unlock their potential.

Why it’s important

This research provides a foundational solution for enabling effective and efficient decentralized multi-agent learning with continuous action spaces, which is critical for scalable AI applications.

What changes

The ability to design communication-free, robust policies for decentralized multi-agent systems reduces design complexity and improves performance in continuous state-action environments, especially where collisions are costly.
