GetNextSolution()

virtual void GetNextSolution ( Assignment *const  assignment )

pure virtual

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

Initialize()

virtual void Initialize ( Assignment *const  assignment )

pure virtual

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

RegisterNewSolution()

virtual void RegisterNewSolution ( Assignment *const  assignment )

pure virtual

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

SyncNeeded()

virtual bool SyncNeeded ( Assignment *const  local_assignment )

pure virtual

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