Class MleanCoPReasoner

java.lang.Object

org.tweetyproject.logics.ml.reasoner.AbstractMlReasoner

org.tweetyproject.logics.ml.reasoner.MleanCoPReasoner

All Implemented Interfaces:

QualitativeReasoner<MlBeliefSet,FolFormula>, Reasoner<java.lang.Boolean,MlBeliefSet,FolFormula>

public class MleanCoPReasoner
extends AbstractMlReasoner

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).
