Two new arXiv papers explore advancements in actor-critic reinforcement learning algorithms. The first paper, though later withdrawn, proposed an optimal sample complexity of O(ε−2) for single-timescale actor-critic methods by using a sample buffer and momentum. The second paper introduces a novel optimistic actor-critic algorithm for low-rank MDPs that relies solely on policy evaluation, achieving improved sample complexity without computationally expensive oracles.
