Dynamic Programming divides the original problem into subproblems, and then complete the whole task by recursively conquering these subproblems. The key idea of DP, and of reinforcement learning generally, is the use of value functions to organize an…

1,Introduction 1.1 What is Dynamic Programming? Dynamic:某个问题是由序列化状态组成,状态step-by-step的改变,从而可以step-by-step的来解这个问题.     Programming:是在已知环境动力学的基础上进行评估和控制,具体来说就是在了解包括状态和行为空间.转移概率矩阵.奖励等信息的基础上判断一个给定策略的价值函数,或判断一个策略的优劣并最终找到最优的策略和最优价值函数.     动态规划算法把求解复杂问题分解为求解…

Model-Based and Model-Free In the previous several posts, we mainly talked about Model-Based Reinforcement Learning. The biggest assumption for Model-Based learning is the whole knowledge of the environment is given, but it is unrealistic in real lif…

Dictum:  A man who is willing to be a slave, who does not know the power of freedom. -- Beck 动态规划(Dynamic Programming, DP)是基于模型的方法,即在给定一个利用MDP描述的完备的环境模型下可以计算出最优策略的优化算法. DP的两种性质:1.最优子结构:问题的最优解法可以被分为若干个子问题:2.重叠子问题:子问题之间存在递归关系,解法是可以被重复利用的.在强化学习中,MDP满足两个…

We began our study of algorithmic techniques with greedy algorithms, which in some sense form the most natural approach to algorithm design. Faced with a new computational problem, we've seen that it's not hard to propose multiple possible greedy alg…

传送门 Description Dynamic Programming, short for DP, is the favorite of iSea. It is a method for solving complex problems by breaking them down into simpler sub-problems. It is applicable to problems exhibiting the properties of overlapping sub-problem…
