Example 1 with CAATLiteral

use of com.dat3m.dartagnan.solver.caat.reasoning.CAATLiteral in project Dat3M by hernanponcedeleon.

the class CAATSolver method computeInconsistencyReasons.

// ======================================== Reason computation ==============================================
private DNF<CAATLiteral> computeInconsistencyReasons(List<Constraint> violatedConstraints) {
    List<Conjunction<CAATLiteral>> reasons = new ArrayList<>();
    for (Constraint constraint : violatedConstraints) {
        reasons.addAll(reasoner.computeViolationReasons(constraint).getCubes());
    }
    stats.numComputedReasons += reasons.size();
    // The conversion to DNF removes duplicates and dominated clauses
    DNF<CAATLiteral> result = new DNF<>(reasons);
    stats.numComputedReducedReasons += result.getNumberOfCubes();
