Clausal relations and {C}-clones

Power algebras: clones and relations

Every operation or relation on a base set A can be "lifted" to the power set P ( A ) . In this paper clones of operations and corresponding invariant relations are studied under this process of lifting (e.g. the clone generated by all lifted operations of a clone is characterized internally by 6-closure (Thm. 2.2) and externally by special invariant relations (Thm. 2.4, 3.3)). Generalizations t...

A Combination of Clausal and Non Clausal Temporal Logic Programs

We have developped Tokio interpreter[5] for rst order Inteval Temporal Logic[11] and an automatic theorem prover [6, 7] for Propositional Interval Temporal Logic. The veri er features deterministic tableau expansion and binary decision tree representation of subterms. Combining these, we can avoid repeated similar clausal form time constraints, and it is possible to execute wider range of speci...

Rewrite Methods for Clausal and Non-Clausal Theorem Proving

Effective theorem provers are essential for automatic verification and generation of programs. The conventional resolution strategies, albeit complete, are inefficient. On the other hand, special purpose methods, such as term rewriting systems for solving word problems, are relatively efficient but applicable to only limited classes of problems. In this paper, a simple canonical set of rewrite ...
