The CCC window |

As you can see in the upper part of the window, there are 86 lessons and 15 couplings, resulting in over 2.8 million combinations that need to be analyzed.
The middle part of the window
The middle part of the window shows a table of all CCCs listed in rows. The first column contains the total number of periods per week involved in each chain. The figures on the right are the lesson numbers of the lessons involved in the chains. The table also displays the abbreviated names of teachers in brackets next to some of the elements. The purpose of this function is described in a later chapter.
2. Click on "8 (New)" in the first row of the middle part of the window (see figure).
The CCC details window
The bottom part of the window - the details window – displays the details of the lesson selected in the middle part of the window. The example shows that the cells for lesson numbers and the number of periods per week are now shaded light blue. Several other cells are now shaded red.
The details window now displays the following information: the elements involved in lesson 8 with a total of 2 periods per week are the class 2b and the teacher Newton (abbreviated name "New").
Lesson 6 with one period per week, by contrast, involves several classes (2a, 2b, 3a, 3b and 4) and teacher Callas.
Some lessons such as lesson 74 (3 periods per week) may only involve one class (here class 4), but several teachers (Curie and Newton).
The cells shaded red highlight the reason why the displayed lesson cannot be scheduled at the same time as the lesson selected in the middle part of the window. Lesson 6, for instance, cannot be scheduled at the same time as lesson 8 since both lessons involve the class 2b. Lesson 10, by contrast, involves a different class, but the same teacher (Newton), and therefore cannot be scheduled at the same time as lesson 8, either.
