Would be more readable to explicitely return None instead of just using pass, but I guess this works as well

Added in latest fork

No, I did not use this one. The one you linked describes Round Robin, the ones I used listed three or so other algorithms and did not involve round robin.
I cannot find it now tho.

2 years later its like 2 chicken wings 8|

@hobovsky could you please share a link to those algorithms?

You have to write you own custom exception class:

What a painful kata! Like it!

It says that I have the ability to edit/approve the kata, but I'm a little reluctant to muck about with approving/editing/creating things. I would like to first get more comfortable wth the established codewars processes, policies, conventions etc. Hence not yet a single kata done by me.

Would any of the power users be so kind as to give me a rundown of what's ok and what's not in terms of editing/approving katas, etc.? Or even just point me to the right documentation perhaps?

Thanks for this! I'll have to have a look at those Zombie solutions that pass here.

I've tried some RR solutions from Zombie apocalypse kata here, and it managed to pass in ~10 seconds, so on a verge of timing out, but still doable. Maybe you need to improve your implementation?

My solution is slightly faster than RR, runs in ~8.5s, and is based on another algorithm found in some scientific paper on the topic. The paper contained a couple of more algorithms, but I could not get them working, only the most basic one (but, apparently, still sometimes better than RR).

Generally, there's quite a few materials and papers online with various approaches to the problem, up to some insanely high values (and equally insane algorithms).

About ranks, you are right, they cannot be changed in an easy way. But since this kata has not many solutions yet, maybe something could be done. It would hjust have to be decided which kata shold be taken in what direction.

Wow, the optimization requirements are insane! The Round-Robin alogrithm doesn't work for this.. Can someone point me in the right direction (i.e. should I try to optimize the standard RR algorithm, or is there something else I ought to be googling for?)

By the way, I don't know if kyu rankings can be changed post-factum, but, given that this is essentially the same problem (bar the optimization constraints) as the Zombie one https://www.codewars.com/kata/5d9b52214a336600216bbd0e/python, maybe this could be 3kyu (or the Zombie one 5 kyu)?

The fact that your code runs fine when you click "Test" means only that it is passing the few listed examples in the sample tests. It does not mean your code runs correctly for every single test case. What likely happened is - your code was wrong and failed on one of the broader test cases that are only available when you click "Attempt".

Try to troubleshoot and see where it's failing. Hint: adding print statements to your code can help.

Marking this as resolved.

Just click "Attempt" instead of "Test"
