Abstract This work proposes an alternative definition of the so-called program transformers, used to obtain reduction axioms in the Logic of Communication and Change. Our proposal uses an elegant matrix treatment of Brzozowski’s equational method instead of Kleene’s translation from finite automata to regular expressions. The two alternatives are shown to be equivalent, with Brzozowski’s method having the advantage of being computationally more efficient.

JELIA Conference 2006 Conference Paper
Abstract n -tableaux [1] and δ -resolution [2], which are based, respectively, on semantic tableaux and resolution, have been properly used for the resolution of abductive problems. The tool we present is a Prolog implementation of an abductive solver which combines both calculi to attack first order abductive problems by reducing them to finite versions, that is, propositional rewritings of the problems which presuppose a context representable with finite models with a known cardinality.
