Fuzzy star functions, probabilistic automata and their approximation by nonprobabilistic automata
Azaria Paz · 1967
Let Sigma* be the set of all tapes over Sigma and let psi : Sigma * $\rarr$ [0, 1]. The problem of approximating such functions (which can be defined, in particular, by probabilistic automata) by nonprobabilistic automata is investigated, in several aspects.
