hi there,

i know about round robin because of chess tournaments.

it is like everybody against everybody, but in chess is double turn because once you play as white and one more time as black with every single opponent.

i know round robin algorithms exist.

there are also round robin schheduling algorithms.

i think you should look at one already made, but maybe in another programming language.

please, look at these web searches:

and maybe, if you are lucky enough, here might be lying your answer:

the actual searches are:

round robin tournament algorithm

round robin scheduling algorithm

these two are actually google saved searches

but this one is mine

round robin algorithm sql

good luck,
