On the rank page, CLK has the point value 1.20; however, a number of people have scores of 1.30 on it. Is this a bug, or are competitors supposed to get more than 1.20 on it?

There is some missprint in rules, I'll try to fix it later. The scoring for classic problem starts from (nominal+0.1).

Now, this contest's problems are similar to the problems on acm.uva, where everbody on lots of problems has got 0.00 sec. time. Too boring.

As one of the "zero timers", I agree that CHOMP would be much better if the size of the chocolate bar was larger. I don´t think it would be right to change the size of the problem during the contest, but it would be nice to change it when it appears on the main problem list.

Some zero times has been eliminated, it seems there was a rejudge for the problem. But this contest's name should be "The big precomputation contest", as all of these are solvable by precomputation:
2: Problems Collection (Volume 3), no input
3: RegExp Master, no input
4: The Longest Chain, no input
5: Markov Algorithm, no input
7: Autoarchive, no input
8: Chomp (there's input, but you can get 0.00 time by precomputation.)

And this is from 9 problems set. I wouldn't call it interesting, but you know. I haven't seen this on other contests so far.

Nice, so the available time is reduced on this problem. It is sad, because if you haven't precomputed the problem, then you have got a little chance to solve the problem:
my not precomputed code used 11.15 sec. (the time limit=50 seconds), but now this is a TLE. Sad and very confusing. But a luck, that I've got a precomputed code.

My Haskell 0.01s solution uses no precomputation, just a clever trick smile

My zero time solution uses pre-computation. My first submission is not precomputed and takes 0.05s. I'm much prouder of the latter and I would love to try to improve it, but when I saw all those 0.00 I deduced (wrongly, it seems, as several 0,00s disappeared) that lots of people were using precomputation, so I decided to try it.

Well, this spoiled some of the fun...

I can only say that using your code and idea make my work possible..for that I am going to use some other technique
