public class OptimizeVar
extends SearchMonitor

This class encapsulates an objective. It requires the direction
(minimize or maximize), the variable to optimize, and the
improvement step.

Method Details

getCPtr

protected static long getCPtr(OptimizeVar obj)

finalize

protected void finalize()

Overrides:

finalize in class SearchMonitor

delete

public void delete()

Overrides:

delete in class SearchMonitor

keepAliveDecisionBuilder

public void keepAliveDecisionBuilder(DecisionBuilder db)

Overrides:

keepAliveDecisionBuilder in class SearchMonitor

best

public long best()

Returns the best value found during search.

var

public IntVar var()

Returns the variable that is optimized.

acceptDelta

public boolean acceptDelta(Assignment delta,
 Assignment deltadelta)

Internal methods.

Overrides:

acceptDelta in class SearchMonitor

enterSearch

public void enterSearch()

Description copied from class: SearchMonitor

Beginning of the search.

Overrides:

enterSearch in class SearchMonitor

beginNextDecision

public void beginNextDecision(DecisionBuilder db)

Description copied from class: SearchMonitor

Before calling DecisionBuilder::Next.

Overrides:

beginNextDecision in class SearchMonitor

refuteDecision

public void refuteDecision(Decision d)

Description copied from class: SearchMonitor

Before refuting the decision.

Overrides:

refuteDecision in class SearchMonitor

atSolution

public boolean atSolution()

Description copied from class: SearchMonitor

This method is called when a valid solution is found. If the
return value is true, then search will resume after. If the result
is false, then search will stop there.

Overrides:

atSolution in class SearchMonitor

acceptSolution

public boolean acceptSolution()

Description copied from class: SearchMonitor

This method is called when a solution is found. It asserts whether the
solution is valid. A value of false indicates that the solution
should be discarded.

Overrides:

acceptSolution in class SearchMonitor

print

public String print()

toString

public String toString()

Overrides:

toString in class BaseObject

accept

public void accept(ModelVisitor visitor)

Description copied from class: SearchMonitor

Accepts the given model visitor.

Overrides:

accept in class SearchMonitor

applyBound

public void applyBound()
