Lüttgen, G. and Mendler, M. (2002) The intuitionism behind statecharts steps. ACM Transactions on Computational Logic, 3 (1). pp. 1-41. ISSN 1529-3785Full text not available from this repository.
The semantics of Statecharts macro steps, as introduced by Pnueli and Shalev , lacks compositionality. This article first analyzes the compositionality problem and traces it back to the invalidity of the Law of the Excluded Middle. It then characterizes the semantics via a particular class of linear intuitionistic Kripke models. This yields, for the first time in the literature, a simple fully abstract semantics that interprets Pnueli and Shalev's concept of failure naturally. The results not only give insight into the semantic subtleties of Statecharts, but also provide a basis for an implementation, for developing algebraic theories for macro steps, and for comparing different Statecharts variants.
