Bipartite checking using Graph Colouring and Breadth First Search (BFS)

The algorithm to determine whether a graph is bipartite or not uses the concept of graph colouring and BFS and finds it in O(V+E) time complexity on using an adjacency list and O(V^2) on using adjacency matrix. It is used to decode codewords and model situations in cloud computing and big data

Overview of Graph Colouring Algorithms

In this introductory article on Graph Colouring, we explore topics such as vertex colouring, edge colouring, face colouring, chromatic number, k colouring, loop, edge, chromatic polynomial, total colouring and various algorithmic techniques for graph colouring.

Graph Coloring Greedy Algorithm

In this article, we have explored the greedy algorithm for graph colouring. graph coloring is a special case of graph labeling ; it is an assignment of labels traditionally called "colors" to elements of a graph subject to certain constraints.

Wigderson Graph Colouring Algorithm

Wigderson Algorithm is a graph colouring algorithm to color any n-vertex 3-colorable graph with O(√n) colors, and more generally to color any k-colorable graph. In this article, we have explored this wonderful graph colouring article in depth.
