Changes

In the Changes screen, you can see changes made to the timetable. You can compare the current timetable with the Initial, Best, or Selected timetable. To undo a change, click on it and click on the Assign button in the Suggestions screen which will pop up.

Hint: To compare two saved solutions, load one solution into the solver (using Timetables page) and then select the second one (also using Timetables page).
