WebSep 15, 2024 · Let $\Gamma $ be a graph of valency at least four whose automorphism group contains a minimally vertex-transitive subgroup G.It is proved that $\Gamma $ admits a nowhere-zero $3$ -flow if one of the following two conditions holds: (i) $\Gamma $ is of order twice an odd number and G contains a central involution; (ii) G is a direct product … WebThe WeightMap has to map each edge from E to nonnegative number, and each edge from ET to -weight of its reversed edge. The algorithm is described in Network Flows . This algorithm starts with empty flow and in each round augments the shortest path (in terms of weight) in the residual graph. In order to find the cost of the result flow use ...

Nowhere-zero flows reduce to flows with M¨obius complications … In graph theory, a flow network (also known as a transportation network) is a directed graph where each edge has a capacity and each edge receives a flow. The amount of flow on an edge cannot exceed the capacity of the edge. Often in operations research, a directed graph is called a network, the vertices are called nodes and the edges are called arcs. A flow must satisfy the restriction that the amount of flow into a node equals the amount of flow out of it, unless it is a s…
