edges-to-adjacency-list

Converts a collection of edges in a graph to an adjacency list representation. For the more general operation on simplicial complexes, use the stars module.

Example

var e2a = require("edges-to-adjacency-list")
 
console.log(e2a([
  [0, 1],
  [1, 2],
  [2, 3]
]))

Output:

[ [1],
  [0, 2],
  [1, 3],
  [2]
]

Install

npm install edges-to-adjacency-list

API

require("edges-to-adjacency-list")(edges[, numVertices])

Converts a collection of edges to an adjacency list representation.

• edges are the edges of the graph
• numVertices is an optional parameter giving the number of vertices in the graph

Returns An array encoding the adjacency list of the graph

Note Repeated edges will be combined.
