keeping_degseq: 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.

Author

Tamas Nepusz and Gabor Csardi

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)))
