Ccc2013

[t68]

is it difficult?

[Panphobia]

it was more difficult than past ones for me, havent you done it?

[Unnamed]

How did you guys do? I got pretty low

[aldld]

Did anybody else have problems with the online grader? I somehow failed every test case on the grader for S1, yet when I compared my solution to others' it always gave the exact same result as theirs, yet they somehow got that one.

Not to mention that it took over an hour for the solutions to be graded.

I'm not sure if I can go into detail right at this moment, but this combined with a whole bunch of other things going wrong resulted in me getting a really really low score

The grader doesn't even work.
0/10, would not use again.
Grade F--.

i got the first three right in java lol,and then the grade messed up for q5 worked for test data but got 0/15 on grader

[coolgod]

The grader worked in the morning and at lunch it was 20 min(according to notice) delay between feedback.
During the afternoon 20 min feedback delay turned in 90 (according to their notice on site.). In reality any solution after 3:20 (when we started) had no feedback provided.
Getting 1-4 perfect with feedback is much easier than without.

oh nice what did you do for q4? what algorithm did you use?

Please don't discuss the problems until the end of the week.

can i discuss that freaking awesome judge system?
they used some advanced technology that made 90 minutes to 4 hours

I'll wait before giving details about the questions, but I hope I can discuss the grading system because this really needs to be addressed. There are more problems with the judging system than just the time.

The day before the competition I did some tests at home with the online grader (with the 2012 questions available). For Python, something as simple as adding a class that does nothing causes the program to fail. Compare these two screenshots:

Honestly this is ridiculous. This competition shouldn't even play a role in scholarship or university admission decisions if they can't even have a working grader. It would probably at least be easier to maintain if their system was more like that of Project Euler or Google Code Jam, where you do the actual running of the program on your own system. https://code.google.com/codejam/quickstart.html

Edit: Another thing worth mentioning: The printed problem booklet allows for 1 minute per test case, however the online grader cuts it off at 1-2 seconds... (5s for problem S5)

^ Agree
I got TLE on grader
but it's still inside 1 minute limit
What's the point to make such a online grader?
Witch one is the real instruction?

Where is official explanation ?

Best CCC ever!!!
Not only does the grader not give any response in time, it also marks almost everything wrong !!!
Only if it happened to everyone, not just the people who used it later.
I mean, it would be unfair for those to suffer instant feedback because they are in different timezone, right?
Defnitely fair!

10/10
would definitely come again!!!!

Guys, cut them some slack. Writing an autograder is tough, and this was the first time they've used this system. It's also harder to grade interpreted languages like Python than compiled languages like C++ and Pascal (don't even get me started on Java). I have complete confidence that the CEMC will sort out these issues and that everyone will be graded fairly.
