Let teams compete by making them create hard instances and fast solvers for problems of your choice. Then pitch these instances and solvers against one another. All language-agnostic.
Makes the number of rounds in iterated battles default to 3 instead of 5, and makes it go to the cap if it was stepped over instead of iterating up to it. Unfortunately, the latter change doesn't actually have a big impact in real-world-ish cases. E.g. here are the number of fights measured over 1000 battles with probabilistic teams:
But it still is better behaviour so it's good to make it work like this.
