Class MleanCoPReasoner

java.lang.Object

net.sf.tweety.logics.ml.reasoner.AbstractModalReasoner

net.sf.tweety.logics.ml.reasoner.MleanCoPReasoner

All Implemented Interfaces:

net.sf.tweety.commons.QualitativeReasoner<ModalBeliefSet,net.sf.tweety.logics.fol.syntax.FolFormula>, net.sf.tweety.commons.Reasoner<Boolean,ModalBeliefSet,net.sf.tweety.logics.fol.syntax.FolFormula>

public class MleanCoPReasoner
extends AbstractModalReasoner

Invokes MleanCoP (http://www.leancop.de/mleancop/), a compact automated theorem prover for modal first-order logic based on the clausal connection calculus. It checks whether a given formula is valid.
NOTE: Make sure to set the PROVER_PATH variable in the mleancop.sh script to the location of the mleancop files (= the Prolog files).
