Return the Turan Graph

The Turan Graph is a complete multipartite graph on $n$ vertices with $r$ disjoint subsets. It is the graph with the edges for any graph with $n$ vertices and $r$ disjoint subsets.

Given $n$ and $r$, we generate a complete multipartite graph with $r-(n mod r)$ partitions of size $n/r$, rounded down, and $n mod r$ partitions of size $n/r+1$, rounded down.

Parameters
  • n (int) – The number of vertices.

  • r (int) – The number of partitions. Must be less than or equal to n.

Notes

Must satisfy $1 <= r <= n$. The graph has $(r-1)(n^2)/(2r)$ edges, rounded down.
