WebAug 23, 2024 · Step 1 − Arrange the vertices of the graph in some order. Step 2 − Choose the first vertex and color it with the first color. Step 3 − Choose the next vertex and color it with the lowest numbered color that has not been colored on any vertices adjacent to it. If all the adjacent vertices are colored with this color, assign a new color to it. WebcolorMap( [Region Regions], Colors ) :- %% color that region (in a way that satisfies adjacency constraints) colorRegion(Region,Colors), %% color the rest of the map colorMap(Regions,Colors).

WebA more efficient Prolog program can be written by interleaving choices and constraints, but this requires the programmer to think in terms of the operational behaviour of the program on this particular map. The same effect can be achieved much more cleanly by using the program of figure 4 with a new definition: ne(X,Y) :- X~=Y.
