Method Detail

violation

protected boolean violation(Placement value)

getValue

public double getValue(Assignment<Lecture,Placement> assignment,
                       Placement value,
                       Set<Placement> conflicts)

Description copied from interface: Criterion

Value of a proposed assignment (including hard conflicts)

Parameters:

assignment - current assignment

value - given value

conflicts - values conflicting with the given value

Returns:

change in this criterion value when assigned

getBounds

public double[] getBounds(Assignment<Lecture,Placement> assignment)

Description copied from interface: Criterion

Bounds (minimum and maximum) estimate for the value

Specified by:

getBounds in interface Criterion<Lecture,Placement>

Overrides:

getBounds in class AbstractCriterion<Lecture,Placement>

Parameters:

assignment - current assignment

Returns:

minimum and maximum of the criterion value

getBounds

public double[] getBounds(Assignment<Lecture,Placement> assignment,
                          Collection<Lecture> variables)

Description copied from interface: Criterion

Value bounds (minimum and maximum) of the criterion on a part of the problem

Specified by:

getBounds in interface Criterion<Lecture,Placement>

Overrides:

getBounds in class AbstractCriterion<Lecture,Placement>

Parameters:

assignment - current assignment

variables - list of problem variables

Returns:
