摘要: In a seminal paper Lin and Reiter introduced the notion of progression for basic action theories in situation calculus. The idea is to replace an initial database by new set sentences which reflect changes due action. Unfortunately, requires second-order logic general. this paper, we introduce strong progression, slight variant that has intended properties, show case actions have only local effects, always first-order representable. Moreover, restricted class local-effect axioms how construct finite.
