Key actions include adding constraints (`AddMaximumConstraint`, `AddObjectiveConstraint`, `AddProductConstraint`), creating variables/constraints (`CreateNewConstraint`, `CreateNewPositiveVariable`), and manipulating variables (`SetVariableBounds`, `SetVariableName`). It also handles objective functions (`Set/GetObjectiveCoefficient`, `ClearObjective`) and allows retrieving values/bounds (`GetValue`, `GetVariableLowerBound`). Other capabilities include clearing data, checking solver type, and solving with time limits (`Solve`).\n"],null,["# RoutingGlopWrapper\n\nC++ Reference: class
