Strongly connected components (SCC) are the maximally connected subgraphs of a directed graph where every node is reachable from every other node (in other words, there exists a path between every node in the subgraph). Neptune Analytics implements this algorithm using a modified multi-step approac...
strongly connected componentIn this paper, an efficient page rank (PR) exact algorithm is proposed, which can improve the computation efficiency without sacrificing results accuracy. The existing exact algorithms are generally based on the original power method (PM). In order to reduce the number ...

For any positive integer k, a simple connected graph G is cyclically k-edge-connected if for any edge cut X with |X|<k, at most one component of G−X contains a cycle. A cycle C in a graph G is dominating if every edge of G has at least one end on C, in other words, G...

(strongly connected components), the nodes in which are reachable to each other.By exploiting the property of SCC,some theories are proposed,based on which the computation iterations can be constrained on these SCC subgraphs.Our algorithm can reduce lots of I/Os and save a large amount of ...
Once the adjacency matrix has been composed, the lagrangian matrix is calculated to obtain the connected components of the network. In the physical sense, each connected component is understood as a zone of interaction between sites. Finally, the eigenvalue centrality is calculated for each of the...
