We propose a new simple and natural algorithm for learning the optimal [Formula: see text]-value function of discounted-cost Markov decision process (MDP) when transition kernels are unknown. Unlike classical algorithms MDPs, such as text]-learning actor-critic algorithms, this does not depend on stochastic approximation-based method. show that our algorithm, which we call empirical iteration c...

We propose a new simple and natural algorithm for learning the optimal Q-value function of a discounted-cost Markov Decision Process (MDP) when the transition kernels are unknown. Unlike the classical learning algorithms for MDPs, such as Q-learning and ‘actor-critic’ algorithms, this algorithm doesn’t depend on a stochastic approximation-based method. We show that our algorithm, which we call ...

Do CEO values matter? Most researchers say yes, but few have been able to empirically prove that. Using the Q-sort method to measure CEO values and HLM to test the effects of CEO values played on middle manager responses in 42 Chinese companies, we found that CEO values affect the manager’s attitudinal responses, but not their job performance as rated by their superiors. Our results also show t...
