Member Function Documentation

GetNextSolution()

virtual void operations_research::SolutionPool::GetNextSolution ( Assignment * assignment )

pure virtual

This method is called when the local search starts a new neighborhood to initialize the default assignment.

Implemented in operations_research::DefaultSolutionPool.

Initialize()

virtual void operations_research::SolutionPool::Initialize ( Assignment * assignment )

pure virtual

This method is called to initialize the solution pool with the assignment from the local search.

Implemented in operations_research::DefaultSolutionPool.

RegisterNewSolution()

virtual void operations_research::SolutionPool::RegisterNewSolution ( Assignment * assignment )

pure virtual

This method is called when a new solution has been accepted by the local search.

Implemented in operations_research::DefaultSolutionPool.

SyncNeeded()

virtual bool operations_research::SolutionPool::SyncNeeded ( Assignment * local_assignment )

pure virtual

This method checks if the local solution needs to be updated with an external one.

Implemented in operations_research::DefaultSolutionPool.
