## Class TimetableModel

- java.lang.Object
- - net.sf.cpsolver.ifs.model.Model<Activity,Location>
  - - net.sf.cpsolver.ifs.example.tt.TimetableModel

-     public class TimetableModel
      extends Model<Activity,Location>

  Simple Timetabling Problem.
  The problem is modelled in such a way that every lecture was represented by a variable, resource as a constraint and every possible location of an activity in the time and space was represented by a single value. It means that a value stands for a selection of the time (starting time slot), and one of the available rooms. Binary dependencies are of course represented as constraints as well.
