Detailed Description

A container that allows to accumulate variables and weights to generate a static DecisionBuilder that uses weights to prioritize the branching decisions (by decreasing weight).

Member Function Documentation

AddVariableTarget()

void operations_research::FinalizerVariables::AddVariableTarget	(	IntVar *	var,
		int64_t	target )

Add a variable to set the closest possible to the target value in the solution finalizer.

Definition at line 841 of file routing_decision_builders.cc.

AddVariableToMaximize()

void operations_research::FinalizerVariables::AddVariableToMaximize

(

IntVar *

var

)

Adds a variable to maximize in the solution finalizer (see above for information on the solution finalizer).

Definition at line 848 of file routing_decision_builders.cc.

AddVariableToMinimize()

void operations_research::FinalizerVariables::AddVariableToMinimize

(

IntVar *

var

)

Adds a variable to minimize in the solution finalizer. The solution finalizer is called each time a solution is found during the search and allows to instantiate secondary variables (such as dimension cumul variables).

Definition at line 852 of file routing_decision_builders.cc.

AddWeightedVariableTarget()

void operations_research::FinalizerVariables::AddWeightedVariableTarget	(	IntVar *	var,
		int64_t	target,
		int64_t	cost )

FinalizerVariables.

Same as above with a weighted priority: the higher the cost, the more priority it has to be set close to the target value.

Definition at line 813 of file routing_decision_builders.cc.

AddWeightedVariableToMaximize()

void operations_research::FinalizerVariables::AddWeightedVariableToMaximize	(	IntVar *	var,
		int64_t	cost )

Adds a variable to maximize in the solution finalizer, with a weighted priority: the higher the more priority it has.

Definition at line 836 of file routing_decision_builders.cc.

AddWeightedVariableToMinimize()

void operations_research::FinalizerVariables::AddWeightedVariableToMinimize	(	IntVar *	var,
		int64_t	cost )

Adds a variable to minimize in the solution finalizer, with a weighted priority: the higher the more priority it has.

Definition at line 831 of file routing_decision_builders.cc.
