In this paper I argue that we do not understand the process of default reasoning. A number of examples are given which serve to distinguish di erent default reasoning systems. It ...
In this work we extend the work of Dean, Kaelbling, Kirman and Nicholson on planning under time constraints in stochastic domains to handle more complicated scheduling problems. I...
Research on nonmonotonic and default reasoning has identified several important criteria for preferring alternative default inferences. The theories of reasoning based on each of...
Definite Clause Grammars (DCGs) have proved valuable to computational linguists since they can be used to specify phrase structured grammars. It is well known how to encode DCGs i...
The logic programming language framework Kernel Andorra Prolog is de ned by a formal computation model. In Kernel Andorra Prolog, general combinations of concurrent reactive langu...
Although Warren's method for the evaluation in Prolog of expressions with higherorder functions appears to have been neglected, it is of great value. Warren's paper need...
