WebNov 26, 2024 · I am trying to solve the classic graph coloring problem using python PuLP. We have n nodes, a collection of edges in the form edges = [ (node1, node2), (node2, node4), ...], and we are trying to find the minimum number of node colors so that no connected nodes share a color. My implementation works, but is slow. WebAug 18, 2024 · Since we for starters are only showing one category and one color, you'll have to wait for the subsequent steps to see the real effects. But here's the same plot now with color_discrete_sequence=px.colors.qualitative.Alphabet as per step 1: 1. Change the color sequence used by px with. color_discrete_sequence=px.colors.qualitative.Alphabet

For example, in the graph mentioned above vertices 1 and 2 cannot have the same color because they have an edge connecting them. However, vertices 2 and 3 can have the same color because they are not connected.
