Class EqualStudentWeights

java.lang.Object

net.sf.cpsolver.studentsct.weights.PriorityStudentWeights

net.sf.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.
