This function returns a goal that assigns a possible resource as the selected one for an alternative resource constraint.

• If the second argument is an instance of IloAltResSet, it considers all the constraints on that instance of IloAltResSet.
• If the second argument is an instance of IloResource, it considers all the constraints on instances of IloAltResSet for which that resource is a possible alternative.
• If the second argument is an IloResourceSelector, it considers all the constraints on instances of IloAltResSet for which that resource is a possible alternative.

The goal uses the selector possibleSel to choose the resource. If no argument of type IloResourceSelector is given, the goal uses the default selector, IloSelAltRes. The goal selects posted and metaposted alternative resource constraints in arbitrary order. To customize this behavior it is necessary to directly use the Scheduler Engine classes IlcAssignAlternative and IloSelector<IlcAltResConstraint>.

Implementation

See IlcAssignAlternative for an example of how this function can be defined.
