The ratings have been updated.


Apparently there was already a problem in the archive by the same name (and hence the same slug/URL). The slug for this new problem has been updated. You should see the right problem now.

I faced my most bad experience on Toph during yesterday’s contest. Toph seriously needs some improvements. Because it’s now contains a lot of international contestants. Each Open-for-All contests gathers 400 or 500 contestants and lot of submissions at a time. That’s why everyone was getting queued yesterday. Now I will talk about some other issues.

I couldn’t use the Compile, Test and Custom Test feature during yesterday’s contest. Toph was showing this error.

That’s why I submitted the solutions directly then (without compiling, testing).

And now I see my rating became 1625.
But Rating History is showing 1624.

Thanks for reporting the rounding issue with rating. Apparently your current rating is 1624.9429397203194. And, the chart was using the floor function instead of the round function.
