XML Stats are near!

[fpnc]

Dear all!

I'm glad to announce that XML stats are really near. Look at this example: you get a list of solved problems (each with your position in that problem's ranklist), and list of tried problems (with # of submissions), with some other information. Note that this is an example and it is not exactly the real updated information. I'll explain that hosts later (just tech stuff).

I'd like to see all of your wishes for useful stats in this thread. Please, tell me what do you think, and give me suggestions for this example.

Code: Select all

Great~~
Can we also sort the solved problem by "volume" or "position in ranking"?

[Anadan]

Hi.
It would be nice if you add the sum of positions in problem's ranklist for
all solved problems.
Moreover, I suggest to sort authors in ranklist by number of solved
problems, second, by this sum of places and only then by submissions.

TO fpnc: That looks great! I especially like the <Not Accepted> part, because that information can be used to compile a list of work still to be done. I guess the numbers are error codes (1=WA, 3=TL, or something like that).

It also would be nice if the information on http://acm.uva.es/cgi-bin/OnlineJudge?ProblemsList could be presented in this fashion (not instead of, but in addition to).

As an extra request: Some more detail about the solved problems (run time and solve date), like on the problemstat page would be handy, although it would add an extra level to the XML:

Code: Select all

    <Problem host="0" contest="0" id="100">
         <Place>2637</Place>
         <Runtime>0:00.456</Runtime>
         <SolveDate>17/02/2003 23:37:54</SolveDate>
    </Problem> 
 

I'm looking forward to it!

[fpnc]

...I guess the numbers are error codes (1=WA, 3=TL, or something like that)....

Really it is the number of times you've sent it. Although this was a preliminar sample and it can be better as your example:

Code: Select all

    <Problem host="0" contest="0" id="100">
         <Place>2637</Place>
         <Runtime>0:00.456</Runtime>
         <SolveDate>17/02/2003 23:37:54</SolveDate>
    </Problem> 
 

Any more information for that extra level? Any other extra levels?

[little joey]

Hmm.
Some general information about the problems, in addition to the overview on ProblemsList, like, per problem:
- problem title;
- total no. of solvers;
- total no. of submissions;
- avg. runtime;
- multi input (yes/no);
- special judge (yes/no);
- fix (yes/no);

You could have two XML-files then, one with general information on the problems (in addition to ProblemsList):

Code: Select all

<ProblemList>
  <LastUpdated>17/02/2003 23:37:54</LastUpdated>
  ....
  <SolvedProblems>
    <Problem Id="100">
      <Title>3n+1</Title>
      <Solvers>5001</Solvers>
      <Submissions>23456</Submissions>
      ....
    </Problem>
  </SolvedProblems>
  <UnsolvedProblems>
    <Problem Id="10402">
        ....
    </Problem>
  </UnsolvedProblems>
</ProblemList>

And one per user, along the lines of your proposal with my additions, called UserStatus. Offcourse those two files can be merged into one.

I Guess this covers about all the information one could wish. I don't know if all this information can be accessed easily though...

[Caesum]

this was 9 months ago, any progress or update on the position ?

[playerX]

I'm just posting to ask the same as Caesum (as his post was ignored)...

[felix_halim]

This XML feature would be awesome.
But why it took a long time to be implemented?
I really looking forward for this feature...

[technobug]

hmmm... and what would we do with xml stats?
i would rather get a better looking and functional overview of the problemset and other pages than pure xml stats.

appart from that, if someone had the time, one could code some xslt in order to show the stats in a nice way... but would it take another 9 months? my baby is already born... should i start my plans for the second one? just joking

dont take it hard... everyone knows this is just a way of doing something nice for the contest community, so its based on spare time.... and i believe we dont have a lot of such heh?

xml bring portability to the stats, then those sites which use scripts to get stats from the current uva, can use the xml to do it, lowering the judge's load a lot.
when this is done, I guess I'll code an open source script to access the xml, as an hobby of course.

[technobug]

its easier to write an xslt template......

[playerX]

well, probably yes.. .but with a script you can manipulate the info the way you want it, do statistics comparsion, ranklists based on instituitions, etc...

[Grow]

maybe before xml stats will be available, just one extra info about user on ?AuthorInfo page should be added : rank -> it's very annoying to find specific user in the ranklist ...
