Return the Turan Graph

The Turan Graph is a complete multipartite graph on $n$ nodes with $r$ disjoint subsets. That is, edges connect each node to every node not in its subset.

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

Parameters:

• n (int) – The number of nodes.

• 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.
