Split Vertices in Vertex Colouring and Their Application in Developing a Solution to the Faculty Timetable Problem

The idea of split vertices is introduced in this paper and a start made to determine those vertices which should be split in order that the chromatic number may be reduced. This idea of splitting or subdividing a vertex was used to develop a faculty timetable, i.e. to specify the times at which courses should be held so that all suitable combinations required by students could be taken. This was applied to the Faculty of Science of the American University in Cairo using the data for the first-year students.

Received April 1985.
