And 42 is still under the hill.

I just got 43 ... but I am afraid the last 3 steps will be hard ... (maybe there is nonzero tolerance ...)

It works according to the definition. Don't forget that the memory is shared. The thread 0 has stack pointer pointing further than the thread 1, so thread 0 writes before thread 1 reaches the position and thread 1 rewrites ones by zeros.

This challenge is actually much easier than the number of solvers suggests.

There is already a lot of good hints here, and note that there are 32 columns.

I have left this challenge alone for a long time. Recently I have decided to make some progress. Frequency analysis showed the uniqueness of the symbols. OK, I have decided to read the symbols ... I have googled the matrix font and wow ... signs, e decimal point. ... Why was I so blind and have not ...

Well then it is not a correct solution. Correct means: You give the answer, it is accepted, finished.

Well then it is not a correct puzzle

seriously: DOES there exist any CORRECT solution with 24 or less??

Yep, just te last step took me 2 years ... as there is just a probabilistic solution with rather small probability of success.

(If I remember well )

code "!" returns 'failed to flood correctly' is incorrect. (finished with wrong result)
code "0c" returns 'is incorrect.' (cycle limit exceeded)
code "+" returns 'is incorrect.' (execution error)
intended answer returns 'is correct'. (finished with correct result)

Hmm, this thread is old but for me the stated problem is still relevant. My Program works fine on some sample inputs, including the one shown on the challenge-page and an empty grid. I'm always below 50k cycles, but the Program is not accepted (not flooding correctly). Is there a limitation to the ...

Hey ElleXuzZ, I got the same problem some time (wow, several years already) ago. Posted a similar question in another deluge-thread here: http://www.hacker.org/forum/viewtopic.php?t=1095 Never got a reply, nor did I find a solution that is accepted. @Hippo, as you solved it and are still around, do...

Yep, the input format is as you have written.

ahh man, I've got so far with this. I've spotted the clever trick and found the hidden data inside, and I'd already used a tool eluded to earlier (always do with PNG puzzles) to look at the chunks, but nothing is leaping out at me. I must use the data I've found in the file now somehow, but I got n...

Congrats and respect to your patience.

Did any solver used better than (3/20)^5 success probability approach?
