This is pretty awesome. I am curious though, does this in any way use the same algorithm as the project that inspired this (https://xviniette.github.io/FlappyLearning/). That one appears to be vastly quicker at learning (reached over 13 million and counting at generation 18).

Discussion of the original: https://news.ycombinator.com/item?id=12917538 Seems to have the same problem as the original where its not actually converging towards a solution but randomly stumbling onto it.

Is there a qualitative difference? I was under the impression that neuro networks worked by converging to a solution BY randomly stumbling into it? Is my rudimentary understanding off this off?

Why is there only ever one (sometimes two/three) decent players every generation? Most will end up dying after one or two poles... how come once the algorithm gets decent there are many more making through the game along with the best one?

(Also, I'd like "number of taps per game segment" be a weight... fall until the very last second then a couple of quick taps - none of this "spamming to keep level" stuff: where's the style? ;)

Actually, I think that the one that you linked to does converge towards a solution. This new one does not.
