Elitism doesn't work as it should

Originally discussed at #4 (comment)

After introducing elitism which pushed bestHuman from the previous generation as the first element of the new one, I would expect the first human in the list always to have the score not worse than the best score of the previous generation. However, it's not happening.

I blamed it on the motorNoise but after reducing it to zero the incorrect behavior of the system still persisted.

Can it be some floating point errors? Any bugs in BOX2D?

what affect does body static vs dynamic have?

"b2.Body.b2_staticBody" - Is there any value in this line? looks like it is immediately contradicted...

evolutionSimulator/src/human.js

Line 30 in fd2a15a

this.bodyDef.type = b2.Body.b2_staticBody;

Speed as input

The current speed of the human should be an input node of the network - as different moves are required to start going from standing still compared to the moves needed to continue walking. That means that even if the human makes a successful couple of first steps, it is bound to fall after that.

(And I just want this damn thing to start walking already!!! 😄)

Can you post some good or interesting genomes?

I've run it for 1500+ generations and don't get beyond 3 steps. It would be interesting to see what the best strategies found have been. People could just post https://gist.github.com/ links in this issue thread...
