Swapping periods |

Periods highlighted green (green cells occupied by a period) can be swapped with other periods highlighted green Drop a period on a green cell and a window will appear where you can specify if you wish to swap the period or if you wish to create a conflict.
Swap suggestions
Swap suggestions can be displayed via the 'Suggested swaps' function in the timetable window. 2-way and 3-way swaps are suggested for the class. The 'Gain' column indicates whether the timetable would be improve (positive values) or deteriorate (negative values) based on the data entered.
The 'Conseqnc.' column displays the worst conflict that the swap in question would cause if the timetable is likely to see a deterioration. If, on the other hand, the timetable is likely to see an improvement (positive value in the 'Gain' column) the category where the largest improvement is likely to take place will be displayed.
Possible swap suggestions are indicated in the timetable by red arrows. Clicking on the <Swap button> performs the selected swap.
Cross-class suggestions
It is often necessary to perform swaps across several classes. To do this, check the box ‘With class leaps' in the 'Suggested swaps' window.
Example:
The German period for class 1b on Mo-5 (Monday, 5th period) is to be swapped. The swap displayed in the figure would bring an improvement of 238 points ('Gain' column). The potential gain is high because this would remove a core time violation (time request). However, it can only be performed without a conflict if a second swap is effected at the same time.
Teacher Rubens, who teaches German to class 1b, has a lesson planned with class 1a in Monday-5. The so-called leap class is therefore 1a and is indicated in the 'Leap cl.' column. The possibilities of moving this lesson to where Rubens takes class 1a are displayed in the lower section of the 'Suggested swaps' window. The best possibility would however lead to a deterioration in the schedule of class 1a of 66 points since it would result in an unallowed double period of German. The difference in the evaluations of both swaps (+238 for the swap for 1b and -66 for the swap for 1a) is displayed in the 'Total' column (+172).
Only different teachers
If a teacher takes a class for more than one subject is it often undesirable for swaps to be offered between these subjects. Checking the 'Only different teachers' box results in such swaps not being displayed.
