Tick this option to delete all teacher swaps carried out in previous optimisation runs. This means that each subject will again be taught by the teacher originally assigned to the lesson under "Lesson | Teachers".
After a successful teacher swap, a display of all swapped and originally assigned teachers can be viewed via "Scheduling | Diagnosis" . The figure on the left shows a situation where the "?-Teacher" function (i.e. teachers suitably qualified to teach the subject) is active and teacher "New" was replaced by "Gauss" for lesson 94.
The lesson details window displays the current and the replaced teacher (see figure).
