A student model description language and its synthesis method are presented. The language called SMDL is based on a logic programming language taking 4 truth values such as true, ...
The past decade has seen an explosion of work on calculi of explicit substitutions. Numerous work has illustrated the usefulness of these calculi for practical notions like the im...
This paper deals with a class of Prolog programs, called context-free term transformations (CFT). We present a polynomial time algorithm to identify a subclass of CFT, whose progr...
Mobile agent technology is an emerging technology that allows easier design, implementation, and maintenance of distributed systems. Mobility enables agents to reduce network load,...
The SLG-WAM of XSB Prolog soundly implements the Well-Founded Semantics (WFS) for logic programs, but in a few pathological cases its engine treats atoms as undefined that are true...
