Temporal difference and policy search methods for reinforcement learning: An empirical comparison

Reinforcement learning (RL) methods have become popular in recent years because of their ability to solve complex tasks with minimal feedback. Both genetic algorithms (GAs) and temporal difference (TD) methods have proven effective at solving difficult RL problems, but few rigorous comparisons have been conducted. Thus, no general guidelines describing the methods' relative strengths and weaknesses are available. This paper summarizes a detailed empirical comparison between a GA and a TD method in ...
