Body: <p>I am fairly new to RL and I compete in AWS DeepRacer student league. The main task there is to create a reward function. All the hyperparameters and action space are fixed. So far, I know how to shape a single component like speed or steering. I always do like steer_reward^2 or speed^2. But when I try to combine the components together, I am not seeing good results. Is it best to mutliply or add components and are there any resource where I find various maximization functions?</p>

Comments.Text: @ArayKarjauv Nope. I am trying find out functions that have a good global minimum or maximum where the variables of the functions are the speed or steering or other params.
