J - graph and cycles
WebA weighted graph is one in which each edge e is assigned a nonnegative number w ( e ), called the weight of e. The weight w ( G) of a weighted graph G is the sum of the … Web22 feb. 1996 · 1. Introduction A cycle packing cg in a (directed) graph is defined in [6] as the vertex disjoint union of elementary (directed) cycles. The size of cg equals the number Ic of vertices covered by the packing. The packing cg is a maximal cycle packing provided no cycle is disjoint from cg and cg is a maximum cycle packing provided leg] is maximum.

Web24 nov. 2024 · If a graph is a bipartite graph then it’ll never contain odd cycles. In graph , a random cycle would be . Another one is . The length of the cycle is defined as the number of distinct vertices it contains. In both of the above cycles, the number of vertices is . Hence these are even cycles. The subgraphs of a bipartite graph are also bipartite.

Let G = ( V , E ) be a claw-free graph of order n and let W be a subset of V with W ≥ 3 k, where k is a positive integer.
