The proposed reinforcement learning-based dynamic multi-objective evolutionary algorithm (in short for RL-DMOEA) is presented in this section. . Compared with traditional RL, MORL requires the agent to obtain a policy that optimizes two or more objectives simultaneously. Because reinforcement learning minimizes the cumulative cost over all time steps, it essentially minimizes the sum of objective values over all iterations, which is the same as the meta-loss. In this project, your Pacman agent will find paths through his maze world, both to reach a particular location and to collect food efficiently. population of multi-objective solutions. Introduction.
