Method Details

compare

public int compare(S solution1, S solution2)

Compares two solutions.

Specified by:

compare in interface java.util.Comparator<S extends Solution<?>>

Parameters:

solution1 - Object representing the first Solution.

solution2 - Object representing the second Solution.

Returns:

-1, or 0, or 1 if solution1 dominates solution2, both are non-dominated, or solution1 is dominated by solution2, respectively.
