During one of my random walks in our library I came across the following paper: R.C. Conant and W.R. Ashby, Every Good Regulator of a System Must be a Model of that System, Int. J. of Systems Science, Vol. 1, 89-97, 1970. From the abstract: ".. a theorem is presented which shows, under very broad conditions, that any regulator that is maximally both successful and simple *must* be isomorphic with the system being regulated .." (I've not yet read it in detail (not even xeroxed it) but from browsing I can tell that it uses only basic automata theory and conditional probabilities).

Advisor: I wonder how it took you so long.. Student: ... Advisor: BTW, have you already gone through a 'Fuzzy Set Period'? Student: Oh yes, long ago, even before my Logic Programming times.. ============================================================================
