Method Summary

Modifier and Type	Method	Description
static <V> V	copy(V object)
static IObjectiveManager<IntVar>	makeObjectiveManager(IntVar objective, ResolutionPolicy policy)	Define the variable to optimize (maximize or minimize) By default, the manager uses IObjectiveManager.setStrictDynamicCut() to avoid exploring worse solutions.
static IObjectiveManager<RealVar>	makeObjectiveManager(RealVar objective, ResolutionPolicy policy, double precision)	Define the variable to optimize (maximize or minimize) By default, the manager uses IObjectiveManager.setStrictDynamicCut() to avoid exploring worse solutions.
static IObjectiveManager<Variable>	SAT()	Define a manager for satisfaction problems.

Method Detail

SAT

public static IObjectiveManager<Variable> SAT()

Define a manager for satisfaction problems.

Returns:

a singleton object

makeObjectiveManager

public static IObjectiveManager<IntVar> makeObjectiveManager(IntVar objective,
                                                             ResolutionPolicy policy)

Define the variable to optimize (maximize or minimize) By default, the manager uses IObjectiveManager.setStrictDynamicCut() to avoid exploring worse solutions.

Parameters:

objective - variable to optimize

policy - {ResolutionPolicy.MINIMIZE/ResolutionPolicy.MAXIMIZE

Returns:

the objective manager

Throws:

IllegalArgumentException - if the policy is ResolutionPolicy.SATISFACTION.

makeObjectiveManager

public static IObjectiveManager<RealVar> makeObjectiveManager(RealVar objective,
                                                              ResolutionPolicy policy,
                                                              double precision)

Define the variable to optimize (maximize or minimize) By default, the manager uses IObjectiveManager.setStrictDynamicCut() to avoid exploring worse solutions.

Parameters:

objective - variable to optimize

policy - {ResolutionPolicy.MINIMIZE/ResolutionPolicy.MAXIMIZE

Returns:

the objective manager

Throws:

IllegalArgumentException - if the policy is ResolutionPolicy.SATISFACTION.

copy

public static <V> V copy(V object)

Parameters:

object - to copy

Returns:

copy built by a copy constructor if one exists, otherwise the parameter.
