public interface SolutionComparator

IFS solution comparator.

The solution comparator compares two solutions: the current solution and the best solution found. This comparison can be based on several criteria. For example, it can lexicographically order solutions according to the number of unassigned variables (smaller number is better) and the number of violated soft constraints.
