Post Server problem on 590 - Maximum execution time exceeded Reply with quote
There's a bug in server configuration, I cannot solve 590 lvl. Every time I submit a solution I get:
<br />
<b>Fatal error</b>: Maximum execution time of 30 seconds exceeded in <b>/home/hacker_apache/html/hacker/html/cross/cross.php</b> on line <b>124</b><br />
What can I do? Is there any active admin?

I had the same problem, with alternating line in the error message.
But try number 21 to submit my answer was successful :)
Hopefully next levels won't cause such problems.

Please try again. We have a faster solution checker now.

Thank You!
I couldn't submit my solution for level 634, now it took only 7 seconds to get the next level.
Well done.

@Zeta: Very nice. Does that mean, that now the path is open for more levels?

The solution checker is still written in PHP. I guess the checker would hit the 30 seconds boundary again with an 800x800 board. Smile Who else is interested in more levels?

I'm interested. It's always good to have more levels!

That's more than enough to promote better-than-O(n) solvers.

Does anybody have o(n^3) solution?
Reducing multiplicative constant by 128 does not count ...

Yes there are some. You could see it on the statistical charts, back then, when they were working. On some charts there was a straight line up, meaning that the time between two solved levels was very small, even on the last levels (You could see the chart by clicking on a player level in the score tables. The level scores are still linked but only lead to an empty site).

This inspired me to search this solution and eventually i found it (its even better than O(n)). Now that you know i hope you also get inspired to search for it Smile

Fortunately I neednot to investigate it Wink ... Applying techniques for sparse matrices could probably help a lot (as the initial matrix could be constructed such that most of the rows will contain just 4-5 nonzeros ... ).
