      • isSatisfiable

        public abstract boolean isSatisfiable​(Collection<net.sf.tweety.logics.pl.syntax.PlFormula> formulas)
        Checks whether the given set of formulas is satisfiable.
        Parameters:
        formulas - a set of formulas.
        Returns:
        "true" if the set is consistent.
