strongly-connected-components

Given a directed graph, splits it into strongly connected components.

Example

var scc = require("strongly-connected-components")

var adjacencyList = [
  [4], // 0
  [0,2], // 1
  [1,3], // 2
  [2], // 3
  [1], // 4
  [4,6], // 5
  [5,2], // 6
  [7,6,3], // 7
]

console.log(scc(adjacencyList))

Install

npm install strongly-connected-components

API

require("strongly-connected-components")(adjacencyList)

Computes the strongly connected components of a graph using Tarjan's algorithm.

• adjacencyList is an array of lists representing the directed edges of the graph

Returns An object containing:

• components: an array of arrays representing the partitioning of the vertices in the graph into connected components.
• adjacencyList: an array lists representing the directed edges of the directed acyclic graph between the strongly connected components
