Yoink these prompts

Prompt 1

Explain how an Echo State Network could be trained in 100 seconds to steer a robot toward an energy source using distance and color sensor inputs.

Prompt 2

Help me design a genetic algorithm to train a 1000-neuron controller for a simulated maze-navigating robot with steering limited to 5 degrees per step.

Prompt 3

Walk me through the two equations that govern neural activity flow in an Echo State Network so I can implement one from scratch.

Prompt 4

Suggest a self-contained reinforcement learning approach that doesn't rely on pre-trained models, suitable for a robot with only steering as its output.
