Genetic algorithms, Mona Lisa and JavaScript + Canvas

It seems the default mutation parameters are a bit low, if you increase it it may lead to better results

I think the main problem with this is that it's using a fixed number of polygons, and apparently is mutating their vertice positions.

If it could be changed for a range of polygons (with a range of vertices, let's say from 3-6) maybe it can converge faster (and better)

But it is nonetheless a very nice experiment. GA/GP is one of those things that really can work with "untractable" questions.

I recently entered a competition (February 2013) and used this technique without having seen this blog. I also used webworkers and SVG.

Sorry, FF or Chrome only (because of how I load the webworkers from the same page)

@tlarkworthy - I had a version that did 12 images for each generation and chose the best - It was a better result but it really throttled the CPU and took down the browser on my weaker machine, so went with the single thread.

Different images work best with different polygon sizes, different cut-offs etc. and it's really sensitive. If I change the parent cutoff for example, a simple 0.01 change seems to ruin Mondrian from forming, even after waiting several thousand mutations.
