virtual Decision* operations_research::DecisionBuilder::Next

(

Solver *const

s

)

[pure virtual]

This is the main method of the decision builder class.

It must return a decision (an instance of the class Decision). If it returns NULL, this means that the decision builder has finished its work.

Implemented in operations_research::FindOneNeighbor, operations_research::FastOnePathBuilder, and operations_research::AllUnperformed.

string operations_research::DecisionBuilder::DebugString

(

)

const [virtual]

Decision Builder.

Reimplemented from operations_research::BaseObject.

Reimplemented in operations_research::FindOneNeighbor.

void operations_research::DecisionBuilder::AppendMonitors	(	Solver *const	solver,
		std::vector< SearchMonitor * > *const	extras
	)			[virtual]

This method will be called at the start of the search.

It asks the decision builder if it wants to append search monitors to the list of active monitors for this search. Please note there are no checks at this point for duplication.
