Several high-level programming languages for programming agents and robots have been proposed in recent years. Each of these languages has its own features and merits. It is still...
Logic programming provides a uniform framework in which all aspects of explanation-based generalization and learning may be defined and carried out, but first-order Horn logic i...
Language is primarily a physical, and more particularly a biological phenomenon. To say that it is primarily so is to say that that is how, in the first instance, it presents itse...
We prove that TAUT has a p-optimal proof system if and only if a logic related to least fixed-point logic captures polynomial time on all finite structures. Furthermore, we show ...
We study extensions of first-order logic over the reals with different types of transitive-closure operators as query languages for constraint databases that can be described by...
