Specialization of LocalSearchOperator built from an array of IntVars which specifies the scope of the operator. This class also takes care of storing current variable values in Start(), keeps track of changes done by the operator and builds the delta. The Deactivate() method can be used to perform Large Neighborhood Search.

OnStart() should really be protected, but then SWIG doesn't see it. So we make it public, but only subclasses should access to it (to override it). Redefines MakeNextNeighbor to export a simpler interface. The calls to ApplyChanges() and RevertChanges() are factored in this method, hiding both delta and deltadelta from subclasses which only need to override MakeOneNeighbor(). Therefore this method should not be overridden. Override MakeOneNeighbor() instead.

ortools.constraint_solver.pywrapcp.IntVarLocalSearchOperator.OneNeighbor | ( | self | ) |
Creates a new neighbor. It returns false when the neighborhood is completely explored. MakeNextNeighbor() in a subclass of IntVarLocalSearchOperator.

ortools.constraint_solver.pywrapcp.IntVarLocalSearchOperator.OnStart | ( | self | ) |
Called by Start() after synchronizing the operator with the current assignment. Should be overridden instead of Start() to avoid calling IntVarLocalSearchOperator::Start explicitly.
