In this contribution we propose a variant of a resolution theorem prover which selects resolution steps based on the proportion of models a newly generated clause satisfies compared to all models given in a reference class, which is generated from a subset of the initial clause set. Since the empty clause does not satisfy any models preference is given to(More)
Proof planning is a form of theorem proving in which the proving procedure is viewed as a planning process. The plan operators in proof planning are called methods. In this paper we propose a strategy for heuristically restricting the set of methods to be applied in proof search. It is based on the idea that the plausibility of a method can be estimated by(More)

Proof planning is an application of AI-planning in mathematical domains. The planning operators, called methods, encode proving steps. One of the strength of proof planning comes from the usage of mathematical knowledge that heuristically restricts the search space. Semantically guided proof planning uses semantic information as search control heuristics.(More)
Proof planning [2, 10] is a reasoning process in which mathematical theorem proving is viewed as a planning problem. It incorporates domain-dependent and/or general mathematical knowledge, and shows a great potential in the area where the traditional logicbased theorem proving systems have been typically weak. The plan operator – method – encodes a piece of(More)
The goal-directed forward reasoning is a two step procedure in which the rst step generates a simpliied assumption clause set (or a single assumption clause) that semantically connicts with the negated conclusion, and the second step searches for a refutation between the simpliied assumption and the negated conclusion. In order to form a simpliied(More)
