Class IloIIM

This class offers iterative improvement method (IIM) management facilities in much the same way as the IloSolver class does for pure constraint programming. This class is created from a solver and has the same life cycle as the solver.

This constructor builds an IIM management class from the solver solver. The life cycle of the constructed class will be equivalent to that of the solver. When the solver is destroyed, the IIM management object must no longer be used. If more than one instance of IloIIM is created on the same solver, then these instances will share the same implementation pointer.

This member function returns the solution delta of the neighbor accepted in the local search using neighbor identifier nid. The solution delta is specified by the neighborhood and is the set of extractables which change value together with their new values. This is equivalent to return getNeighborIdentifier(nid).getAtDelta(); The returned delta does not belong to the user, but the neighborhood identifier itself: end() must not be called on it.

This member function returns the index of the neighbor accepted in the local search using neighbor identifier nid. This is equivalent to return getNeighborIdentifier(nid).getAtIndex();

This member function returns the neighborhood identifier used inside search which is extracted from the neighborhood identifier nid used for search specification.

This member functions returns the solver passed at construction time.
