R Documentation

Graph rewiring while preserving the degree distribution

Description

This function can be used together with rewire to randomly rewire the edges while preserving the original graph's degree distribution.

Usage

keeping_degseq(loops = FALSE, niter = 100)

Arguments

loops	Whether to allow destroying and creating loop edges.
niter	Number of rewiring trials to perform.

Details

The rewiring algorithm chooses two arbitrary edges in each step ((a,b) and (c,d)) and substitutes them with (a,d) and (c,b), if they not already exists in the graph. The algorithm does not create multiple edges.

Examples

g <- make_ring(10)
g %>%
  rewire(keeping_degseq(niter = 20)) %>%
  degree()
print_all(rewire(g, with = keeping_degseq(niter = vcount(g) * 10)))
