Policy Iteration for Continuous-Time Average Reward Markov Decision Processes in Polish Spaces

الملخص EN

We study the policy iteration algorithm (PIA) for continuous-time jump Markov decision processes in general state and action spaces.

The corresponding transition rates are allowed to be unbounded, and the reward rates may have neither upper nor lower bounds.

The criterion that we are concerned with is expected average reward.

We propose a set of conditions under which we first establish the average reward optimality equation and present the PIA.

Then under two slightly different sets of conditions we show that the PIA yields the optimal (maximum) reward, an average optimal stationary policy, and a solution to the average reward optimality equation.
