For stochastic adaptive systems important is to consider local ergodic system, Markov chain, local Monte Carlo simulation and maximum entropy method to be more efective.
I was thinking on local ergodic process ( local controllability, local irreducibility). See my paper in Analele Universitati din Timisoara, 1990, Ser. Mat.Inf.
Local controllability, local ergodicity is necessary condition for the system, such that fixed point theorem holds true. The fixed point theorem is the equivalent of the maximum entropy principle. Am I right?
