Method Detail

compare

public int compare(java.lang.Object o1,
                   java.lang.Object o2)

Compares two solutions.

Specified by:

compare in interface java.util.Comparator

Specified by:

compare in interface IConstraintViolationComparator

Parameters:

o1 - Object representing the first Solution.

o2 - Object representing the second Solution.

Returns:

-1, or 0, or 1 if o1 is less than, equal, or greater than o2, respectively.

needToCompare

public boolean needToCompare(Solution s1,
                             Solution s2)

Returns true if solutions s1 and/or s2 violates a number n > 0 of constraints
