The considered problem instances include random, flat, planar, and scale-free graphs, together with some real-world graphs from the fields of timetabling and social networking.

Social Media and Civil Society in Japanve strengths and weaknesses. This chapter now presents a range of problems, both theoretical and practical based, for which such algorithms might be applied. These include face colouring, edge colouring, precolouring, constructing Latin squares, solving Sudoku puzzles, and testing for short circuits

Dalien René Benecke,Sonja Verweyies and other types of educational establishments. As we will see, this problem area can contain a whole host of different constraints, which will often make problems very difficult to tackle. That said, most timetabling problems contain an underlying graph colouring problem, allowing us to use many

Bounds and Constructive Heuristics,triangle and therefore cannot be bipartite [.]. However, as we saw in the previous chapter, even the problem of deciding whether . is .-complete for arbitrary graphs. In this chapter, we will review several upper and lower bounds on the chromatic number. We will also examine five different constructive heuristics for the graph colouring problem.
