#1 Multiagent Stochastic Shortest Path Problem [PDF] [Copy] [Kimi] [REL]

Authors: Martin Jonáš, Antonín Kučera, Vojtěch Kůr, Jan Mačák, Vojtěch Řehák

We introduce and study the multi-agent stochastic shortest path (MSSP) problem, in which k agents strive to reach a target state, aiming to minimize the expected time to reach the target by any agent. We analyze the computational and strategy-complexity of the problem in both autonomous and coordinated settings, and we design efficient strategy-synthesis algorithms. The algorithms are experimentally evaluated on instances of increasing size against natural baselines.
