Hierarchical reinforcement learning can be used to solve curse of dimensionality problem. MAXQ method decomposes the task into gubtasks in different levels through decomposing value function hierarchically, so it can be realized in low dimension space.

• 分层强化学习方法可用于解决维数灾难问题,MAXQ方法通过分层地分解值函效,将任务分解为不同层次上的子任务,从而只需在低维空间中解决问题。
