I am currently using final 6.0 and I used
<constructionHeuristicType>BEST_FIT</constructionHeuristicType> but after I
have run it propmts java.lang.NullPointerException pointing to my
PlanningVariableStrengComparator. Did I miss something? My planning variable
comparator by the way is :
public class MyVariableStrengthComparator implements Comparator<MyVariable>,
Serializable {
public int compare(MyVariable a, MyVariable b) {
return new CompareToBuilder()
.append(a.getId(), b.getId())
.toComparison();
}
}
