graph colouring
<application> A constraint-satisfaction problem often used as a test case
in research, which also turns out to be equivalent to certain real-world
problems (e.g. register allocation). Given a connected graph and a fixed number
of colours, the problem is to assign a colour to each node, subject to the
constraint that any two connected nodes cannot be assigned the same colour. This
is an example of an NP-complete problem.
