Count the Number of Strongly Connected Components

The strongly connected components are the classes of an equivalence relation on the nodes of a directed graph. Two nodes are in the same class if they are connected with directed paths in both direction.

Usage

CountStronglyConnectedComponents(arcSources, arcTargets, numNodes)

Arguments

arcSources

Vector corresponding to the source nodes of a graph's edges

arcTargets

Vector corresponding to the destination nodes of a graph's edges

numNodes

The number of nodes in the graph

Value

An integer defining the number of strongly connected components
