A previous method based on the generalization of the Aihara model is sensitive to the varying degree of the vertices in the graph and there is a strong tendency for the network to form suboptimal limit cycles on regular graphs.

A graph G = (V, E) with χ(G) ≤ 2 is called a 2-colorable graph. A couple of minutes of reflection should convince you that for n ≥ 2, the cycle C2n with 2n vertices is 2-colorable. On the other hand, C3 ≅ K3 is clearly not 2-colorable. Furthermore, no odd cycle C2n + 1 for n ≥ 1 is 2-colorable. hepatic congestion from chf
