In this question, every "game" takes about 5 seconds. Ten thousand runs, maybe eight thousand, are planned. Running these on a single computer would take forever, so I suggested letting competitors and volunteers run some of the games. However, this result in cheating. My question is: should this be allowed?
Yes, but not competitively
The controller should be made available by the person running the KotH, to allow people to test and experiment, however they should not have a part in the final run that determines the winner. It should be up to the original poster to plan ahead of time how they intend to run the game, and if their game takes a long time to run, they should either optimize their controller, or have thought about that before hand (and made a less complex game).
One solution would be to have a cutoff date for entries, and at that point begin running the controller with all available entries, perhaps on a server somewhere, so that it can be left running as long as it needs. Then once the controller has finished, results can be posted.
