Value Iteration的正式过程如下: Iteration on the Bellman optimality backup:第一步就是使用贝尔曼方程去更新价值函数 To retrieve the optimal policy after the value iteration:第二步就是根据得到的收敛的价值函数去计算最优策略 具体的伪码如下:2.2 Value Iteration的适用场景 Action对State的影响和回报 P(State'...

(1)策略迭代方法(Policy Iteration) 为实现策略迭代方法,首先要实现策略评估(Policy Evaluation),目的是为了对给定的策略求取值函数的真值(贝尔曼期望)。 迭代策略评估(Iterative Policy evaluation)的迭代方程如下: image.png 即,当前状态的值函数更新为:在该策略下的期望回报+折扣系数×在该策略下的下一状态的当前值...
it can be solved, for instance, by value iteration. Figure 4.3 shows the change in the value function over successive sweeps of value iteration, and the final policy found, for the case of ph =0 .4. This policy is optimal, but not unique. In fact, there is a whole family of ...

In Python arguments are strictly ‘passed by object’, which means that what happens to the variable within a function will depend on whether it is mutable or immutable. For immutable types (ints,floats, tuples, strings) the objects are immutable, hence they cannot be changed at any point ...
