What is the difference between value iteration and policy iteration? Group of answer choices:

Value iteration:

Policy iteration:

a$.$ the value function V$($s$)$ for each state s is updated by finding the maximum expected value over all possible actions a$,$ represented as Bellman equation b$.$the value function V$($s$)$ is calculated assuming that the agent follows the fixed policy without considering other possible actions, represented as bellman equation remove Max operator. The policy will be update later during policy improvement stage
