“…Quality diversity optimization is a rapidly growing branch of stochastic optimization with applications in generative design [32,27,26], automatic scenario generation in robotics [21,20,19], reinforcement learning [60,62,57,75], damage recovery in robotics [14], and procedural content generation [30,24,78,15,48,73,68,67]. Our paper introduces a new quality diversity algorithm, CMA-MAE, that bridges the gap between single-objective optimization and quality diversity optimization.…”
