Monte-Carlo Search for an Equilibrium in Dec-POMDPs

no code implementations19 May 2023 Yang You, Vincent Thomas, Francis Colas, Olivier Buffet

Decentralized partially observable Markov decision processes (Dec-POMDPs) formalize the problem of designing individual controllers for a group of collaborative agents under stochastic dynamics and partial observability.

Robust Robot Planning for Human-Robot Collaboration

no code implementations27 Feb 2023 Yang You, Vincent Thomas, Francis Colas, Rachid Alami, Olivier Buffet

Based on this, we propose two contributions: 1) an approach to automatically generate an uncertain human behavior (a policy) for each given objective function while accounting for possible robot behaviors; and 2) a robot planning algorithm that is robust to the above-mentioned uncertainties and relies on solving a partially observable Markov decision process (POMDP) obtained by reasoning on a distribution over human behaviors.

Solving infinite-horizon Dec-POMDPs using Finite State Controllers within JESP

no code implementations17 Sep 2021 Yang You, Vincent Thomas, Francis Colas, Olivier Buffet

This paper looks at solving collaborative planning problems formalized as Decentralized POMDPs (Dec-POMDPs) by searching for Nash equilibria, i. e., situations where each agent's policy is a best response to the other agents' (fixed) policies.
