Hi, I'm glad we agree on the benefits of black box testing. As I said before, we completely agree with the sentiment that there's lots of important reasons to make practice available. It's high on our list of priorities and we are working to make that happen ASAP. Best, Pablo On Fri, Apr 13,

I'm talking about opening the visible dataset for those who have passed the tests already. Not a big deal if the participant could compare his solution for the hidden dataset with the results on tests for the visible dataset. As an alternative there could be an option to allow to submit the

There could be a reasonable solution of the problem with testing Hidden after you have solved the Visible. What if the platform would allow the participant to download the whole visible dataset as soon as he has solved it? He has earned the points for his submission of Visible, why not to open

Yeah for these large datasets I find it best to write your own test cases and see how your algorithm run against them. Even np.random.randint(0,1e9,1e5) or something of the sort works well to see how fast (or slow) your algorithm runs. On Sun, Apr 8, 2018, 16:41 Felix Voituret

That's a good point about not being able to test your new solution on the same input that you know you got right, Dmitriy. A few other thoughts: - I don't know whether the UI makes this clear -- note to team, hopefully there's a really clear indication that you still have points from previous

Bartholomew: there is another concern. Let's imagine that I've solved the Visible dataset, and I know for sure that this doesn't solve the Hidden one. I submit the solution, I get the positive verdict, and I start the better implementation. In the old platform I can always compare the results

For me the issue is whether we're looking at something closer to 1e7 or 1e9 operations per second, which has a pretty significant impact on what algorithms can work to solve a problem. On Tue, Apr 10, 2018 at 1:13 PM wrote: > Actually you can figure out for yourself

Actually you can figure out for yourself without running the code if a idea will got TLE or not. It is normally if you know the complexity of your solution and compare it to problem restriction. For example, it is obviously that O(T * n^2) will got TLE in Trouble sort problem, because the size

Yes! Time Limit Exceeded. It's an acronym from the UVA online judge, and/or TopCoder. I admit that I was curious to see if it would be recognized. :-) Felix: That's a really good point. I had half of that realization during the round about D, and I'm glad that you expressed it so clearly. I

Previously you also had to estimate the runtime for your large submission. If you started downloading the input file for large submission, and couldn’t finish before running out of time, you still lose points. The new system however, allows you to submit again if you later find a better solution
