    Succinctness of Hierarchical State Diagrams in Absence ofMessage Passing

    Abstract

    We show a subexponential but superpolynomial lower bound for
    flattening problem for statecharts. The result presented is resistant
    to many variations in statecharts semantics.
    The immediate consequence is that usage of common flattening
    algorithms in the implementations of tools should be carefully
    examined, taking into account presence of signal communication in the
    target language. This specifically affects flattening-based
    strategies for automatic model-based program synthesis.
