Class EqualStudentWeights

java.lang.Object

org.cpsolver.studentsct.weights.PriorityStudentWeights

org.cpsolver.studentsct.weights.EqualStudentWeights

All Implemented Interfaces:

SolutionComparator<Request,Enrollment>, StudentWeights

public class EqualStudentWeights
extends PriorityStudentWeights

Student weight is spread equally among student's course requests. Only alternatives have lower weight. The rest is inherited from PriorityStudentWeights.

Method Detail

getWeight

public double getWeight(Request request)

Overrides:

getWeight in class PriorityStudentWeights

isBetterThanBestSolution

public boolean isBetterThanBestSolution(Solution<Request,Enrollment> currentSolution)

Description copied from interface: SolutionComparator

Compares two solutions. Returns true if the given solution is better than its best ever found solution (see Solution.saveBest() and Solution.restoreBest()).

Specified by:

isBetterThanBestSolution in interface SolutionComparator<Request,Enrollment>

Overrides:

isBetterThanBestSolution in class PriorityStudentWeights

Parameters:

currentSolution - given solution

Returns:

true if the given solution is better than the best ever found solution

isFreeTimeAllowOverlaps

public boolean isFreeTimeAllowOverlaps()

Description copied from interface: StudentWeights

Return true if free time requests allow overlaps

Specified by:

isFreeTimeAllowOverlaps in interface StudentWeights

Overrides:

isFreeTimeAllowOverlaps in class PriorityStudentWeights

Returns:

true if free time overlaps are allowed, but the overlapping time is minimized

main

public static void main(String[] args)

Test case -- run to see the weights for a few courses

Parameters:

args - program arguments
