http://analytictech.com/networks/graphtheory.htm Web1 Introduction Graph theory may be said to have its begin-ning in 1736 when EULER considered the (gen- eral case of the) Königsberg bridge problem: Does there exist a walk crossing each of the seven bridges of Königsberg exactly once?
WebTheorem 2: A given connected graph G is an Euler graph if and only if all vertices of G are of even degree Proof: Suppose that G is and Euler graph. Which contains a closed walk called Euler line. In tracing this walk, observe that every time the walk meets a vertex v it goes through two “new” edges incident on v – with one we entered v ...
