networkx.algorithms.smallworld.lattice_reference

lattice_reference(G, niter=1, D=None, connectivity=True, seed=None)[source]

Latticize the given graph by swapping edges.

Parameters

  • G (graph) – An undirected graph with 4 or more nodes.

  • niter (integer (optional, default 1)) – An edge is rewired approximatively niter times.

  • D (numpy.array (optional, default None)) – Distance to the diagonal matrix.

  • connectivity (boolean (optional, default True)) – Ensure connectivity for the latticized graph when set to True.

  • seed (integer, random_state, or None (default)) – Indicator of random number generation state. See Randomness.

Returns

G – The latticized graph.

Return type

graph

Notes

The implementation is adapted from the algorithm by Sporns et al. 1. which is inspired from the original work by Maslov and Sneppen(2002) 2.
