OJ Board

I have been very busy as well with a new job. I think that the most important thing for Ivor and myself is trying to figure out different ways of solving the same problem to gain speed.

Ivor and I still compete although we have not traded emails for a while (my fault). The nice thing about the ...

Rankings seem to be getting messed up during the past month. For those of us that compete each problem, this kind of removes the reason for the rankings in the first place.

I would like to get this thread a little more exposure:

I believe that others have run into this kind of problem and would like to hear some other comments.

I have used both run-time calculation and pre-calculation. In my career I have had the need for both. Some times you need to calc a sqrt and other times you don't have the time, but have the space for a look-up table. I salute the solver that was able to compress a 1Mb lookup into a 40kb.

At times ...

I have yet to hear anything about the adding any documentation about compiler versions. I hope to soon.

Judge,

Could you add a section to the versions link that shows the compiler versions as well as the online judge version?

I am able to compile my code, however judge response states compiler error. Since I don't know what the version that the judge uses is, I am not able to determine what the ...

It took me awhile to get back to this problem and try out what cooleye is referring to. I now agree that the judge is wrong. There are three different ways to look at this problem (one of them is not consistent with the drawing).

1) B & D are opposite each other - A is floating. The answer that the ...

Cooleye,

Check your geometry again, (2 + sqrt(3))/(5 + sqrt(3)) is correct.

Since this has been a little while since Caesum posted this, I am assuming that he has solved it, so this is for everyone else that has as many problems as I have - since there was no answer to Caesum, I had to ask for help from others who have solved it.

So here goes.

1) 0 < n < 4000. This falls ...

First, I would like to thank all of you at Valladolid for hosting this site and making it the success that it is!

Second, I do have my own opinions about what I would like this site to be, however I have to realize that I am not hosting the site - I am merely using the site. The way the maintainers ...

I believe that the nan problem started when the judge restarted. I never saw or heard about the problem before the judge went to the great judge heaven.

Ivor has a very good idea to make the output of P100 larger than 40k - that is a nice solution to "printf" type of solutions.

Keep up the good ...

The last time I received nan was today, submission number 1063807. I believe that Ivor received a nan the same day, not sure what his submission number was.

I don't believe that rejudging is the issue right now, when it happens - fine. The main issue is that there is still a problem in the timing ...

I recieved a 'nan' as well on 628. Could you decribe your method of timing code execution? Is it just the unix "time" program, or are you doing some kind of messaging of the timing information. nan usually equates to a divide by zero, or something along those lines.

Let us know what we can do to ...

I agree with Ivor, I have no doubt that you are continuing to update and fix the system. Could you give us a little insight as to what is going on and what some of the ideas for fixing thing are - you have a large resource out here of people that can give ideas/resources/code to fix some of these ...

I have recently seen and been involved with several fluke timings for problems. Specifically 100, 371 and 102. Instead of getting a response of 0.000 for time I get "nan" for a response, which translates to 0.000 time in the rankings. The problem seems to have surfaced when the judge was down to run ...
