Reinforcement learning without gradients: evolving agents using Genetic Algorithms

During holidays I wanted to ramp up my reinforcement learning skills. Knowing absolutely nothing about the field, I did a course where I was exposed to Q-learning and its "deep" equivalent (Deep-Q Learning). That's where I got exposed to OpenAI's Gym where they have several environments for the agent to play in and learn from. The course was limited to Deep-Q learning, so as I read more on my own. I realized there are now better algorithms such as policy gradients and its variations (such as Actor-Critic method).
