WebDec 1, 2024 · The code bellow tries to solve the graph coloring problem (k-coloring). I'm really struggling to find its time complexity. It's basically three nested loops. In worst case: Outermost loop runs len (graph) (the size of a given graph - its number of vertices) times. Inner for loop runs num_colors times (number of colors being tested) WebVertex coloring is the most commonly encountered graph coloring problem. The problem states that given m colors, determine a way of coloring the vertices of a graph such that …
