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. 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 915 of file routing_decision_builders.cc.

◆ AddWeightedVariableTarget()

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

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 897 of file routing_decision_builders.cc.

◆ CreateFinalizer()

DecisionBuilder * operations_research::FinalizerVariables::CreateFinalizer ( )

Returns a DecisionBuilder* that sets the variables passed through AddVariableTarget and AddWeightedVariableTarget towards their target, setting weigthed variables by decreasing weight first, then unweighted variables in the order they were added.
