No matter how meticulously we prepare and enter the timetable information, there could be typos, or oversights that creep in. These problems could make a timetable unsolvable if not corrected. In the example below:
This highlights potential problems that we might face in trying to solve the table. Examining T.Jones further:
The image above reflects T. Jones' timetable configuration. T. Jones' teaching schedule:
This shows that we need a minimum of 7 periods per day to cater for this constraint. In this case above, we could actually get away with this!!!
Looking at the required periods per cycle, we see LO and the Zulu/Tsonga/Sotho groups requirements of 2 and 3's respectively in a 5 day cycle, so there is the possibility that we can overlook this validation error.
