In this paper, a dynamic approach to deductive query evaluation is presented which combines the e ects of di erent SIP strategies used for the magic set rewriting technique. Given...
Deduction modulo consists in applying the inference rules of a deductive system modulo a rewrite system over terms and formulæ. This is equivalent to proving within a so-called co...
In deduction modulo, a theory is not represented by a set of axioms but by a congruence on propositions modulo which the inference rules of standard deductive systems--such as for ...
Abstract. The ELAN system is an environment for specifying and prototyping constraint solvers, theorem provers and deduction systems in general. It also provides a framework for ex...
Logical systems in natural deduction style are usually presented in the Gentzen style. A different definition of natural deduction, that corresponds more closely to proofs in ord...
