dominating_set(G, start_with=None)[source]

Finds a dominating set for the graph G.

A dominating set for a graph with node set V is a subset D of V such that every node not in D is adjacent to at least one member of D 1.

Parameters
  • G (NetworkX graph)

  • start_with (node (default=None)) – Node to use as a starting point for the algorithm.

Returns

D – A dominating set for G.

Return type

set

Notes

This function is an implementation of algorithm 7 in 2 which finds some dominating set, not necessarily the smallest one.
