# Round Robin Cyclic Algorithm

Presume people are more used to number series starting with 1 instead of 0, and they want the first pair of the first round to be [1,2].

Then, functionally, the 1'st pair of the r'th round is:

[ 1 , (r+n-1-1) % (n-1) + 2 ], r=1..n-1

and the i'th pair of the r'th round is:

[ (r+i-2) % (n-1) + 2 , (r+n-i-1) % (n-1) + 2 ], r=1..n-1, i=2..n/2

Using these equations here is a version that outputs pairs
