We give a formal semantics for a highly expressive language for representing temporal relationships and events. This language, which we call Versatile Event Logic (VEL), provides ...
In this paper, we present our work on creating a complete set of rules for temporal arithmetic mixing months and days based on the “history-dependent intuition”. Many examples...
Computer science has long been considered to emphasize three distinct perspectives: mathematics, science, and engineering. While the database field has some very strong mathemati...
Abstract. The design of reactive systems must comply with logical correctness (the system does what it is supposed to do) and timeliness (the system has to satisfy a set of tempora...
In this paper, we describe a first-order linear time temporal logic (LTL) model checker based on multiway decision graphs (MDG). We developed a first-order temporal language, LMDG ...
