WebNov 3, 2015 · Basically, a matrix representation of a directed graph is fully connected if only the main diagonal contains zeros, because the main diagonal represents the connection of each vertex with itself. Anything different from this represents a not fully connected graph. So, in a very very simple way: WebStrongly connected components also have a use in other graph algorithms: if you replace every strongly connected component by a single vertex, you get a smaller directed acyclic graph, known as the component graph or condensation (Baase ex. … WebA more interesting problem is to divide a graph into strongly connected components.

WebWe also know that the strongly connected components of the graph can be computed in linear time. The idea is to exploit this fact to compute the transitive closure of the graph. Further, if (x, y) is an edge between two vertices in different strongly connected components, every vertex in y's component is reachable from each vertex in x's component. WebExecute a Pregel-like iterative vertex-parallel abstraction. The user-defined vertex-program vprog is executed in parallel on each vertex receiving any inbound messages and computing a new value for the vertex.
