Create your own four-colored world
Submitted by Ibrahim Cahit Arkut on
Our algorithmic method has been given in three steps. The first two steps are the maximal mono-chromatic and then maximal di-chromatic coloring of the faces in such a way that the resulting uncolored (white) regions of the incomplete two-colored map induce no odd-cycles so that in the (final) third step four coloring of the map has been obtained almost trivially. In order to make the map-coloring algorithm more visible and meaningful let us define the four-color set as
C = {B,G, dB, lB}, where
