Abstract

Working principle of the probabilistic automaton is based on the state transition probability [4], [6]. Construction of the automaton depends on its purpose. We assume that all transitions probabilities are constant[3]. In situations where low levels of information (entropy) suggest assurance solutions, we use interval probabilities (remembering that the sum of the probabilities of transition to the given state must remain equal to 1). This variant generates additional problems, which are: how to prevent the redundancy of the probabilities sum; the physical interpretation of this situation; undervaluing of the probabilities sum; determine the criteria of the structure and parameters optimization (minimization) relative to the semantic resources of formal languages described by the automaton; change in the level of information entropy.
