#2This is fun! Does it learn the same from many short, low scoring runs as it does with fewer, longer, high scoring runs?

#3my experience is at 50 the first smart bird appeared, then at 121 they became consistently good.

#4This 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).

#5It made it to 25k by gen 160. Then it deviated an started losing again. Gen 250 was virtually unstoppable, hitting 120k. Watching gen 251 right now, and it just crushed 100k... 150k... 200k... 242k. Wow. And Gen 252 is killing it too. Seems to have found a sweet spot.

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?

#8After being stuck at ~24k for a long time on the 1051st round it scored 83170. Seems to learn very slowly, perhaps the new generations are too random?

#9Why 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.
