strongComp

Identify Strongly Connected Components

The strongly connected components in a directed graph are identified and returned as a list.

Keywords
models
Usage
strongComp(g)
Arguments
g
graph with edgemode “directed”.
Details

Tarjan's algorithm is used to determine all strongly connected components of a directed graph.

Value

A list whose length is the number of strongly connected components in g. Each element of the list is a vector of the node labels for the nodes in that component.
