Yes, I try to do it as cheaply as possible. abs(r1-r2) + abs(g1-g2) + abs(b1-b2)

Yep, cartoon images seem to be tough for this particular algorithm to optimize. The first velociraptor I tried was a stop sign from XKCD and it failed miserably. Though you never know, I also thought black&white Darwin image was hopeles

I know about this problem, just I'm getting too tired to be able to debug it. It's almost 5am here. If it does something weird, just reset it by forced reload (Ctrl-F5). Stay tuned tomorrow for DNA import/export, it's like 80% done. [Edit]

I don't do anything smart. These are just brute force mutations, always the same. The only parameter tuning I did was to try several numbers of vertices per polygon for about 15 minutes and from there on I just used the one (6 vertices) tha

You can run it locally if it is on your local webserver ( http://localhost ) instead of just filesystem (file://). That's how I work on it (XAMPP). http://en.wikipedia.org/wiki/Xampp

Yup, that was the idea. I just added MIT License [1] to the source. Everything is in one self-contained HTML file (sans images). Feel free to improve it :). [1] http://en.wikipedia.org/wiki/Mit_license

I envy you :). You may try to run it on different images, I just added new experimental feature: you can set your own target image. This does crash JavaScript sometimes on some images (for unknown reasons). If this happens, just reload the

I reimplemented the algorithm from [1] in JavaScript using canvas.getImageData for fitness computation. It's far from perfect, but it seems to work. So far I'm at around 1/30th of the original iterations (took ~1 hour) and it already looks

Yup, that's what I ment. This is what I do when posting Wikipedia urls with parens here. For parsing parens problem, heuristics proposed by lacker seems reasonable. Anyway, I guess like 99% of broken parens cases here would be Wikipedia lin

It's possible to get around using escape sequences. In Python: import urllib print urllib.quote("en.wikipedia.org/wiki/Smart_(automobile)") It looks ugly, but it makes links clickable: http://en.wikipedia.org/wiki/Smart_%28automob

Ah yes, you are right. I also didn't realize it's not even genetic programming as DNA seems to be just polygon data, not polygon-drawing programs. BTW your comment was eponysterical :) http://mssv.net/wiki.cgi?Eponysterical

If we want to be more precise, this type of optimization is called simulated annealing (population = 1, no cross-over, just mutations): "At each step, the SA heuristic considers some neighbour s' of the current state s, and probabilistic

So if we take a range of estimates for total amount of lithium in the world (4.4M - 165M tons) and "a rule of thumb" of 124 pounds for one vehicle, there is enough lithium in the world for concurrently active 78M - 2.9B vehicles. By some

Google Update is indeed very sneaky. Its installation piggybacks on plenty of Google software (including browser plugins) without telling anything and then it installs a task into Windows Scheduler that keeps respawning it when you kill it.
