Method Detail

compare

int compare(Assignment<Request,Enrollment> assignment,
            Enrollment[] current,
            Enrollment[] best)

Compare two solutions

Parameters:

assignment - current assignment

current - current solution

best - best known solution

Returns:

true if current solution is better than the best one

canImprove

boolean canImprove(Assignment<Request,Enrollment> assignment,
                   int idx,
                   Enrollment[] current,
                   Enrollment[] best)

Bound

Parameters:

assignment - current assignment

idx - current request index

current - current solution

best - best known solution

Returns:

if the current solution can be extended and possibly improve upon the best known solution

getTotalWeight

double getTotalWeight(Assignment<Request,Enrollment> assignment,
                      Enrollment[] enrollments)

For backward compatibility, return a weighted sum

Parameters:

assignment - current assignment

enrollments - current solution

Returns:

solution weight (weighted sum)
