GATE 2023 Question no 55
Let G be a simple, finite, undirected graph with vertex set {v1,...,vn}. Let Δ(G) denote the maximum degree of G and let N = {1, 2,...} denote the set of all possible colors. Color the vertices of G using the following greedy strategy: for i ... colors used is equal to the chromatic number of G. Why is option D also not a solution? Gate answer key shows (A,B) as solutions.
