Solver

Screen description

In the Solver screen, you can load input data to the solver and run the solver in different configurations and modes. The operations available to you and the amount and kind of information displayed will depend on the status of the solver (the first item of the Solver section).

Loading input data

During the loading phase, input data and student information is loaded and the classes which have only one required room and one required time will get them assigned.

For the rest, see above

Current Timetable

An initial timetable is created as soon as you start loading data. Only classes with one required time and one required room get there assignments at this point.

See Solution Properties for the description of the items in this part of the screen.

Best Timetable Found So Far

During the automated timetabling (when the solver is running), the best timetable found so far is saved here. It is the timetable that is presented to the user when he/she stops the solver or when the time-out is reached.

When the user interacts and makes changes, he/she can save intermediate results as "Best Timetable Found So Far" and later come back to this timetable if the current one is not good.

Operations are self-descriptive

Current Timetable

When solver is stopped, the Best Timetable Found So Far is the same as the Current Timetable. From that moment, any manual changes made by the user are applied to the Current Timetable.

Problems

The list of warnings appears if any problem occurred during the data load. If there is a problem during solving, there will be an error message (such as Error: FATAL).

Hint: See Solver Warnings to see a detailed list of warnings and errors that may be produced by the solver. If you see a FATAL message, keep the solver in the memory and use Contact Us (located in Help menu) page to report a problem.
