optimizing the neat with backpropagation ?

[winatawelly]

do you think it is possible to backprop the neat result ? if so what do you think the best way(s) to do that ? thanks!

Yes. As long as the evolved network is differentiable, this can be done. This is not different in any way from optimising a regular neural network, so you should find enough resources online for doing this.
