In a given flow network G= (V,E) and a flow f an augmenting path p is a simple path from source s to sink t in the residual network Gf. By the definition of residual network, we may increase the flow on an edge (u,v) of an augmenting path by up to a capacity Cf (u,v) without violating constraint, on ...
WebDefinitions. A graph is formed by vertices and by edges connecting pairs of vertices, where the vertices can be any kind of object that is connected in pairs by edges. In the case of a directed graph, each edge has an orientation, from one vertex to another vertex.A path in a directed graph is a sequence of edges having the property that the ending vertex of … WebThe girth of a graph is the length of its shortest cycle; this cycle is necessarily chordless. Cages are defined as the smallest regular graphs with given combinations of degree and girth. A peripheral cycle is a cycle in a graph with the property that every two edges not on the cycle can be connected by a path whose interior vertices avoid the ...
