sample_k_regular | R Documentation |
Generate a random graph where each vertex has the same degree.
sample_k_regular(no.of.nodes, k, directed = FALSE, multiple = FALSE)
no.of.nodes |
Integer scalar, the number of vertices in the generated graph. |
k |
Integer scalar, the degree of each vertex in the graph, or the out-degree and in-degree in a directed graph. |
directed |
Logical scalar, whether to create a directed graph. |
multiple |
Logical scalar, whether multiple edges are allowed. |
This game generates a directed or undirected random graph where the degrees of vertices are equal to a predefined constant k. For undirected graphs, at least one of k and the number of vertices must be even.
The game simply uses sample_degseq()
with appropriately
constructed degree sequences.
An igraph graph.

## A simple ring

plot(ring)
## k-regular graphs on 10 vertices, with k=1:9
