Hello Codeforces!
I am in the process of making improvements and updates to the judgment machines. I've read the post https://codeforces.me/blog/entry/94587 and I think, maybe it is a good idea to make such a compilation line -O3 -funroll-loops -march=native -mtune=native
? I haven't done any research that it is definitely better than -O2
and it is best in the general case for CP solutions. In a way, this will only strengthen the gap from Python/PyPy/Java, on the other hand: in pragmas and so you can set up everything. What do you think? What are suggestions to the command line?
P.S. You got it right. Yes, gcc11 std=c++20
, pypy3 64-bit
and more are coming.
