Class TimetableModel

public class TimetableModel
extends Model

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.
