Graph coloring in prolog
WebEngineering; Computer Science; Computer Science questions and answers; Implement the simplest version of the graph coloring algorithm in Prolog. The goal of graph coloring is to add a color to each vertex in such a way that the adjacent vertices (via edge) have assigned different colors. WebThe map maker only has 3 colors to use and no two states which share a border can be colored the same color. Write a program which finds an acceptable assignment of colors to states. Write a Prolog program states/5 which finds an acceptable assignment of colors to the 5 states above states without using a graph as the underlying data structure.
