Why does it happen that if i generate timetables, it may take like 15 mins. The next time i do it while not having cchanged anything, it takes longer. At times, i might have deactivated some constraints but it takes longer.If i happen to cancel a file that was generating and remove some constraints, the file that had run fast will tend to slow down. What really happens?
This had taken 24 mins to finish. Its now almost a hour and i haven't changed anything
Generation is semi-random. It is normal.
Okay
