Greedy coloring c++

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 introduced in an upper bound to the chromatic number of a graph . It provides a greedy algorithm that runs on a static graph. WebThis first fit is a greedy approach in choosing the best color for a vertex that appears dynamically along its edges for a given graph. So, whenever a new vertex appears along with its edges, the new vertex is given a new color with first fit (i.e. the best possible minimum color), without altering the colors already defined for the previous ...

The breadth first search (BFS) will implicitly choose an ordering for you. So the algorithm is correct, but will not always give the optimal coloring (i.e. least number of colours used). A more common ordering is to order the vertices by their degree, known as the Welsh–Powell algorithm.
