Euler's graph
Euler's graph. 6 Jun 2017 ... Abstract. Graph planar adalah suatu graph yang dapat dilukiskan pada bidang sehingga tidak ada garis yang saling berpotongan.The Criterion for Euler Paths Suppose that a graph has an Euler path P. For every vertex v other than the starting and ending vertices, the path P enters v thesamenumber of times that itleaves v (say s times). Therefore, there are 2s edges having v as an endpoint. Therefore, all vertices other than the two endpoints of P must be even vertices. A given connected graph G is a Euler graph if and only if all vertices of G are of even degree and if exactly two nodes have odd degrees then graph has Euler path but not Euler circuit.
