Given that I am still 40 chars away from the top solution for Power of Thor, I was wondering if code golfing solutions are ever re-evaluated once a language update happens or if validation tests change.
The question came up because I read that the old “system()” trick for JS doesn’t work anymore since SpiderMonkey was replaced with NodeJS V8 (a while ago…). So do old solutions using this trick still count? Ignoring the discussion whether it’s cool to use Bash in a JS solution, I’ld consider this case unfair because they had tools at hand that cannot be used any longer (“child_process.exec()” is much longer…).
Similarily, I think I read that a missing validation test was added for Thor for going North (couldn’t find the post anymore, though so I might be wrong). Any solutions that pruned away this path in the past would have an unfair advantage, too…
I am aware that re-running potentially thousands of solutions again is resource intense. Also, I am not sure how Codingame should rank solutions that now aren’t passing 100% anymore - and users might get confused why their solution was ranked down (or up :)). For e.g. Python 2 vs 3, print ‘abc’ vs print(‘abc’) would break a lot of solutions, too I guess (other language’s updates might be even less compatible?).
But I think it would be more interesting to see solutions/rankings for the current state of available language versions and validation tests than to keep solutions that aren’t up to date anymore.
What do you think?
