System Description: The Tableau WorkBench

Abstract:

The Tableau Workbench (TWB) is a generic framework for building automated theorem provers for
arbitrary propositional logics. The TWB has a small core that defines its general architecture, some extra
machinery to specify tableau-based provers and an abstraction language for expressing tableau rules.
This language allows users to ``cut and paste'' tableau rules from textbooks and to specify a search
strategy for applying those rules in a systematic manner. A new logic module defined by a user is
translated and compiled with the proof engine to produce a specialized theorem prover for that logic. The
TWB provides various hooks for implementing blocking techniques using histories and variables, as well
as hooks for utilising/defining optimisation techniques like backjumping, simplification and caching. We
describe the latest version of the TWB which has changed substantially since our system
description in TABLEAU 2003.
