In the related work section of their paper they mention that WANNs are related to genetic programming [1], a subfield of evolutionary algorithms.

Genetic programming is quite a powerful tool. IIRC, a few years ago, a researcher evolved expressions to model the dynamics of a double pendulum based only on measured data. To his surprise he found that the expressions were the Lagrangian of the system.

but a double pendulum isn't complicated at all!

how many floats are there? 2 lengths, 2 initial angles, a 2-dimensional velocity, a mass, and a gravitational field strength? thats like 8 floats...
