Historically, payment model innovations have been examined mostly WebPotential- based reward shaping is a method of providing this knowledge to an agent by additional rewards. Furthermore, if the agent is alone in the environment, it is guaranteed to learn the same behaviour both with and without potential-based reward shaping.

WebThe term shaping in experimental psychology (dating at least as far back as (Skinner 1938)) refers to the idea of rewarding all behavior leading to the desired behavior, in- stead of waiting for the subject to exhibit it autonomously (which, for complex tasks, may take prohibitively long). WebThis paper proves and demonstrates a method of extending potential-based reward shaping to allow dynamic shaping and maintain the guarantees of policy invariance in the single-agent case and consistent Nash equilibria in the multi- agent case.
