Temporal Specification Optimisation for the Event Calculus
Periklis Mantenoglou, Alexander Artikis

Temporal pattern matching tasks require the detection of situations of interest based on streams of symbolic events. The Run-Time Event Calculus (RTEC) is a formal framework that represents situations of interest as time-varying properties called ‘fluents’. Temporal patterns often express ‘Boolean combinations’ of situations; RTEC features two types of fluents that may model such patterns:
