public interface DominanceComparator

Interface for comparing two solutions using a dominance relation. A dominance relation may impose a partial or total ordering on a set of solutions.

Implementations which also implement Comparator impose a total ordering on the set of solutions. However, it is typically the case that (compare(x, y)==0) == (x.equals(y)) does not hold, and the comparator may impose orderings that are inconsistent with equals.

Method Summary

int	compare(Solution solution1, Solution solution2) Compares the two solutions using a dominance relation, returning -1 if solution1 dominates solution2, 1 if solution2 dominates solution1, and 0 if the solutions are non-dominated.

Method Detail

compare

int compare(Solution solution1,
            Solution solution2)

Compares the two solutions using a dominance relation, returning -1 if solution1 dominates solution2, 1 if solution2 dominates solution1, and 0 if the solutions are non-dominated.

Parameters:

solution1 - the first solution

solution2 - the second solution

Returns:

-1 if solution1 dominates solution2, 1 if solution2 dominates solution1, and 0 if the solutions are non-dominated
