Hence a graph containing a complete graph of r vertices is at least r-chromatic. For instance, every graph having a triangle is at least 3- chromatic. A graph consisting of simply one circuit with n ≥ 3 vertices is 2-chromatic if n is even and 3-chromatic if n is ...

WebGraph theory was born in 1736 with Euler’s solution of the Königsberg bridge problem, which asked whether it was possible to plan a walk over the seven bridges of the town without re-tracing one’s steps. Euler realised that the problem could be rephrased in terms of a graph whose vertices corresponded to the four regions of the city, and ...
