... Right, and in the past few hours I've lost a full point in part B, and the only submissions in that time were the 03/01 submissions neither of whom have...
see the bottom of the problem page. You start with a 1 for part b, since its trivial to achieve that. Submissions only shows submissions that improve your...
While using matrices you find online or elsewhere is not allowed, there is a fair amount of literature pertaining to the problem, which provides some good...

You can use standard libaries that are included with standard distributions of whatever language you are using. Other than that though, you should write your...
about the code,i can't understand why you say don't use other ppl code if you want only solution and not code to it. (the ideea is that its lame to CTRL+C...

I think the point in the rule really boils down to good sportsmanship. It's true that it is impossible to tell if a solution was copied (either the solution ...
I think that posting already found results won't change the final contest results. For example, how can you check if a matrix is already known ? BTW, it could...
I know it's a little bit too early, but I would like to know how fast you can compute determinants for part A of the contest. Of course, you don't have to...
To do a total of 100 calcs of det on 59x59 array, all 0's: .0100 seconds To do a total of 100 calcs of det on 59x59 array, all1's: .1101 seconds. There is a...
Yes, nobody can't find if your solutions comes from other's code. But you will have much more fun using the same set of rules as your opponents do. Obviously,...
I also have 2.4 Ghz pentium For 100 all 1's its 0.09 seconds For 100 all 0's also 0.09 seconds This a not very meaningful because the algorithm spots matrices...
I have done a little research about Mathematica and I have found that it uses an O(n^4) algorithm to calculate the determinant of a matrix, where n is the...

... think ... Yes, I've been using that formula, too ;) That's probably also why Lars won't display the scores in high accuracy (and the same applies to Al's...
My two cents would be to point out the following: If you have 50 points then in the morning it drops to 49.5 then someone has beaten one of your scores. You...
The contest has an unexpected level of complexity. The problem is that the contest will end on the 3rd of April, and one month is not sufficient to compete on...
I think part of the challenge is the time limit factor... sure, most solutions will not be the absolute best possible answer for every value of n, but it's...
... I don't agree. First, if the contest was longer, we could have better solutions on all Ns (and perhaps I would have time to setup a distributed project...
I'm not sure why you think having time constraints is inherently bad. Its just part of the contest to manage your time well, focus on what's important, and...

has someone figured out some of the best scores so far and can post it ? This can be done by comparing your score before and after submitting an entry but is...
sorry, if this was discussed before, but why do we have these large ranges here 10..59 , as we are used to have 10..25 from Al ? Is there some interesting...
