K coloring algorithm
Web27 oct. 2014 · 1 It's a common knowledge that coloring vertices of a graph is NP-complete. It's also known that there are efficient greedy algorithms that can get an approximate solution. Why not use these randomized greedy algorithms to calculate a coloring with k colors and then use some slower algorithms to reduce k? Web1 apr. 2011 · Algorithm 1 - one by one, choose a random region, and give it a color that still "fits", i.e. is not a color of any colored neighbor. If you run into a conflict (can't color the …
