چکیده

This paper presents an eecient implementation method for a constructive negation approach in logic programming. The constructive negation approach is reformulated as a derivation rule. An heuristic method for eeciently implementing the derivation rule is presented and the complexity of the heuristic method is analysed.

Constructive Negation in CLP(H)

Inclusion of negation into logic programs is considered traditionally to be painful as the incorporation of full logic negation tends to super-exponential time complexity of the prover. Therefore the alternative approaches to negation in logic programs are studied and among them, the procedural negation as failure sounds to be the most successful and the most widely used. However, with the spre...

A Space Efficient Implementation of a Tableau Calculus for a Logic with a Constructive Negation

A tableau calculus for a logic with constructive negation and an implementation of the related decision procedure is presented. This logic is an extension of Nelson logic and it has been used in the framework of program verification and timing analysis of combinatorial circuits. The decision procedure is tailored to shrink the search space of proofs and it is proved correct by using a semantica...

Negation and Constraint Logic Programming

Almost all constraint logic programming systems include negation, yet nowhere has a sound operational model for negation in CLP been discussed. The SLDNF approach of only allowing ground negative subgoals to execute is very restrictive in constraint logic programming where most variables appearing in a derivation never become ground. By describing a scheme for constructive negation in constrain...

Constructive Failure in Functional-Logic Programming: From Theory to Implementation

Functional-logic programming amalgamates some of the main features of both functional and logic styles into a single paradigm. Nevertheless, negation is a widely investigated feature in logic programming that has not received much attention in such programming style. It is not difficult to incorporate some kind of negation as finite failure for ground goals, but we are interested in a construct...
