这个思路来源于搞了动态规划几十年(也算是理论奠基人之一了)的Dimitri Bertsekas,他所称之为Abstract Dynamic Programming Models。在回答最后的第五节,我再基于个人的观点谈谈学习研究动态规划的意义。 一、定义:两个集合 S,A ;策略映射 \mu ;两个算子 T_\mu,T 本节我们定义为了准确描述动态规划模型必不可少...
Once you have defined the state, you can draw a recursive tree, focus on the optimal substructure and write the transfer equation. That's why I said that the state definition is the core of dynamic programming, and the state of dynamic programming problems is really not easy to see....

Dynamic programming does not work if the subproblems: A. Share resources and thus not independent. B. Cannot be divided in half. C. Overlap. D. Have to be divided too many times to fit into memory. 相关知识点: 试题来源: 解析 A 反馈 收藏 ...
Dynamic programming is a method for solving a complex problem by breaking it down into a collection of simpler subproblems, solving each of those subproblem
However, the initial state and the connection between the upper and lower data must be considered. Many times the problems that can be solved by dynamic programming can also be solved by recursion, but in many cases, the efficiency is not high and memory search may be used. ...
