I have just seen this incredible video in which we can see AI-controlled preys and predators, mutation, genetic succession, and how their population change as they evolve: https://www.youtube.com/watch?v=qwrp3lB-jkQ
But it's based on C++. Taking Pine Script as an example, is there a scripting language that makes building such simulations easier, without the requirement of knowing C languages?
Sounds like you might be more interested in Evolutionary Computation and Genetic Algorithms more than ANNs but these fields cross over in the field of Neuroevolution.
Taking pinescript out of the equation for the moment - Tensorflow.js is an approachable web based framework to start working with ML models, depending on your feeling - you may or may not consider javascript a scripting language, but the learning curve is not as steep as c++.
I’d recommend having a look at the TF Playground for a tour for interactive ML sims using this framework.
