Abstract
The ergodic control problem for semi-Markov processes is reformulated as an optimization problem over the set of suitably defined 'ergodic o ccupation measures.' This set is shown to be closed and convex, with i ts extreme points corresponding to stationary strategies. This leads t o the existence of optimal stationary strategies under additional hypo theses. A pathwise analysis of the joint empirical occupation measures of the state and control processes shows that this optimality is in t he strong (i.e., almost sure) sense.
