WebJul 30, 2024 · C++ Program to Perform Graph Coloring on Bipartite Graphs. A bipartite graph is a graph in which if the graph coloring is possible using two colors i.e.; vertices in a set are colored with the same color. In this program we take a bipartite graph as input and outputs colors of each vertex after coloring the vertices. WebIn graph theory, Welsh Powell is used to implement graph labeling; it is an assignment of labels traditionally called "colors" to elements of a graph subject to certain constraints. In 1967 Welsh and Powell Algorithm …

You can simply use a coloring DFS (Depth-First Search) function. It can be implemented as follows: int color [100005]; //I assume this is the largest input size, initialise all values to -1. vector AdjList [100005]; //Store the neighbours of each ...
