Use a choice variable (COptQuestChoiceVariable) instead. Add it with
OptQuestModel.AddChoiceVariable(String, int). The value of a choice variable is the
number of the selected option, from 1 to the number of options.
Use a sequence variable (COptQuestSequenceVariable) instead. Add it with
OptQuestModel.AddSequenceVariable(String, String[], Integer). A sequence variable gives
the same ranks, from 1 to n, and it also has a top-k mode.
