The study of a two-switch device driving a data file shows all the ways to trigger, maintain, halt an event, to synchronize it with another, or to have it overlap ...

Une procédure de décision pour un problème de satisfiabilité dans un univers ensembliste héréditairement fini

In this paper, we deal with the satisfiability problem for Systems of constraints over hereditarily finite sets This problem is central for integrating sets in programming languages, and particularly for constraint logic programming languages The approach we propose hère is based on reducing Systems of set constraints into Systems ofhnear integer equalities and inequahties (with bounded domain)...
