【Abstract】 This article discusses,theoretically and practically,two issues which showld be paid attentia to when Dynamic programming is employed,that is the separability of the Objective function and the Markov property of the state variable. It analyzes their theoretical significance and also points out how to deal with them practically. It will be helpful for researchers theoretically practically.更多还原
