Analysis of Value Iteration Through Absolute Probability Sequences

Arsenii Mustafin, Sebastien Colla, Alex Olshevsky +1

Value Iteration is a widely used algorithm for solving Markov Decision Processes (MDPs). While previous studies have extensively analyzed its convergence properties, they primarily…

Exploiting Agent Symmetries for Performance Analysis of Distributed Optimization Methods

Sebastien Colla, Julien M. Hendrickx

We show that, in many settings, the worst-case performance of a distributed optimization algorithm is independent of the number of agents in the system, and can thus be computed in…
