A ring is a one-dimensional lattice and this function is a special case
of make_lattice()
.
Arguments
- n
Number of vertices.
- directed
Whether the graph is directed.
- mutual
Whether directed edges are mutual. It is ignored in undirected graphs.
- circular
Whether to create a circular ring. A non-circular ring is essentially a “line”: a tree where every non-leaf vertex has one child.
- ...
Passed to
make_ring()
