Strategy E - overnight optimisation

As the name already implies, this strategy may take very long, however, it brings about the best results in most cases.

Use it only at the very end, i.e. after you have applied all other strategies. The duration of the optimisation run heavily depends on the size of the school and on the number of timetables to be calculated, how many optimisation steps are necessary per timetable and on the capacity of the computer. Therefore it may really take the whole night, i.e. overnight.
