Re-assign original teachers

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 'Teachers | Lessons'.

After a successful teacher swap, all swapped and originally assigned teachers are shown in the diagnosis function ( <Diagnosis> button on the 'Start' tab). The following figure shows a case in which the '?' was replaced by 'Callas' for lesson 35.
