An odd cycle of a logic program is a simple cycle that has an odd number of negative edges in the dependency graph of the program. Similarly, an even cycle is one that has an even...
Abstract. Often graphs are used to investigate properties of logic programs. In general, different graphs represent different kinds of information of the corresponding programs. ...
Compositionality of programsis an important concern in knowledge representation and software development. In the context of Logic Programming, up till now, the issue has mostly be...
A variable is local if it occurs in a clause body but not in its head. Local variables appear naturally in practical logic programming, but they complicate several aspects such as ...
