    caching can reuse SAT solver instances, but experience has shown that it can lead to incorrect results, hence caching is currently disabled

  13. def getSatAssignment(featureModel: BDDFeatureModel, dnf: Iterator[Seq[Int]], lookupName: (Int) ⇒ String): Option[(List[String], List[String])]

    Basically a clone of isSatisfiable(.

    Basically a clone of isSatisfiable(..) that also returns the satisfying assignment (if available). The return value is a Pair where the first element is a list of the feature names set to true. The second element is a list of feature names set to false.

  14. def getSatisfiableAssignmentFromStringSets(fm: BDDFeatureModel, interestingFeatures: Set[SingleFeatureExpr], defEnabledFeatures: Set[String], defDisabledFeatures: Set[String], preferDisabledFeatures: Boolean): Option[(List[SingleFeatureExpr], List[SingleFeatureExpr])]

    takes two sets of strings as parameter (one for true variables and one for false variables).

    takes two sets of strings as parameter (one for true variables and one for false variables). Computes an assignment that satisfies the configuration. Assuming that all variable names appear in the featureModel.
