Saul Posted February 27, 2019 Report Share Posted February 27, 2019 Hi Khurram! The graph coloring problem is an old problem -- it was solved a few decades ago, using a lot of computer work -- the old conjecture that you need only 4 colors was finally proven -- with a lot of computer work. Aubrey is considering a modification -- add the restriction that all lines in the planar graph are lenght one. Then, he purports to show that you need at least 5 colors. 😇 -- Saul Quote Link to comment Share on other sites More sharing options...
