- Hi Folks,
-
- There is a classic problem where a 2-D map of regions needs to be coloured
- in such a way that no adjacent region has the same colour. It turns out
- that the maximum number of colours needed to fill in the map is four. Does
- anyone happen to have a solution to this problem on-line ?
-
- Cheers,
-
- Colin
