@ARTICLE{PapacchiniSchmidt11, AUTHOR = {Papaccini, F. and Schmidt, R. A.}, YEAR = {2011}, TITLE = {A Tableau Calculus for Minimal Modal Model Generation}, JOURNAL = {Electronic Notes in Theoretical Computer Science}, VOLUME = {278}, NUMBER = {3}, PAGES = {159--172}, ABSTRACT = { Model generation and minimal model generation is useful for fault analysis, verification of systems and validation of data models. Whereas for classical propositional and first-order logic several model minimization approaches have been developed and studied, for non-classical logic the topic has been much less studied. In this paper we introduce a minimal model generation calculus for multi-modal logic K(m) and extensions of K(m) with the axioms T and B. The calculus provides a method to generate all and only minimal modal Herbrand models, and each model is generated exactly once. A novelty of the calculus is a non-standard complement splitting rule designed for minimal model generation. Experiments show the rule has the added benefit of reducing the search space. } }
