PPT-Interface Automata

29September2011 Modeling Temporal Behavior of Component Component behaves with Environment Traditional pessimistic approach Environment is free to behave as it wants to Two components are compatible if . Each one tape automaton defines a set of tapes a twotape automaton defines a set of pairs of tapes et cetera The structure of the defined sets is studied Various generalizations of the notion of an automaton are introduced and their relation to the g Muller or Rabin automata The reason is that there exist lan guages which are accepted by some nondeterministic B uchiautomaton but not by any deterministic B uchiautomaton cf section 1 The history of constructions for determinizing B uchi automata THEORY.
