Method Detail

unassigned

protected void unassigned(Assignment<Lecture,Placement> assignment,
                          Placement value)

Description copied from class: AbstractCriterion.ValueContext

Update value when unassigned

Overrides:

unassigned in class AbstractCriterion.ValueContext

Parameters:

assignment - current assignment

value - recently unassigned value

assigned

protected void assigned(Assignment<Lecture,Placement> assignment,
                        Placement value)

Description copied from class: AbstractCriterion.ValueContext

Update value when assigned

Overrides:

assigned in class AbstractCriterion.ValueContext

Parameters:

assignment - current assignment

value - recently assigned value

updateCriterion

public void updateCriterion(Assignment<Lecture,Placement> assignment,
                            InstructorConstraint instructorConstraint,
                            Placement placement)

Method checks or sets the CompactInfo of an InstructorConstraint. It updates the preference of chosen criteria. The update consists of decrementing the criterion value by previous preference, finding the current preference and incrementing the criterion value by the current preference.

Parameters:

assignment - current assignment

instructorConstraint - the Instructor constraint of an instructor checked for criteria

placement - placement of a lecture currently (un)assigned

getCompactInfo

protected InstructorLunchBreak.CompactInfo getCompactInfo(InstructorConstraint constraint)

Get compact info that is associated with an instructor constraint. Create a new one if none has been created yet.

Parameters:

constraint - instructor constraint

Returns:

compact info for the given constraint

updateLunchPenalty

public void updateLunchPenalty(Assignment<Lecture,Placement> assignment,
                               InstructorConstraint constraint,
                               Placement p)

Method updates number of violations in days (Mo, Tue, Wed,..) considering each week in the semester separately. The current number of violations for a day is stored in the CompactInfo.lunchDayViolations of the constraint, which must be set properly before the calling of the method.

Parameters:

assignment - current assignment

constraint - the Instructor constraint of an instructor checked for a lunch break

p - placement of a lecture currently (un)assigned

computeLunchPenalty

public double computeLunchPenalty(Assignment<Lecture,Placement> assignment,
                                  InstructorConstraint constraint)

Method computes number of violations in days (Mo, Tue, Wed,..) considering each week in the semester separately. Updates the compact infos accordingly.

Parameters:

assignment - current assignment

constraint - instructor constraint

Returns:

current penalty for the given instructor
