#### Abstract

In this paper, we propose an approximate relative value learning (ARVL) algorithm for non- parametric MDPs with continuous state space and finite actions and average reward criterion. It is a sampling based algorithm combined with kernel density estimation and function approximation via nearest neighbors. The theoretical analysis is done via a random contraction operator framework and stochastic dominance argument. This is the first such algorithm for continuous state space MDPs with average re- ward criteria with these provable properties which does not require any discretization of state space as far as we know. We then evaluate the proposed algorithm on a benchmark problem numerically.
