CountStronglyConnectedComponents {rlemon}

Count the Number of Strongly Connected Components

Description

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

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
