4-coloring Of Planar Graph. The number of colors needed to properly color any map is now the number of colors needed to color any planar graph. If v has 3 or few neighbours there are at most 3 colours adjacent to v so we can pick. Since uw and v x cannot both be in G as G is a planar graph. Browse discover thousands of brands. To get all possible colorings should be in O2n since in the worst case you will have an exponential number of possibilities to color the image.
Dont know if it. A plane map can be seen as a map on a globe picture 4 and hence 4-colring of planar graph is equivalent to 4s -coloring of the maps on a globe.
