# Questions tagged [value-iteration]

For questions related to the value iteration algorithm, which is a dynamic programming (DP) algorithm used to solve an MDP, that is, it is used to find a policy given the transition and reward functions of the MDP. Value iteration is related to another DP algorithm called policy iteration.

### Reinforcement Learning (Fitted Q): Qn on Concept & Implementation

I hope to get some clarifications on Fitted Q-Learning ('FQL'). My Research So Far I've read Sutton's book (specifically, chp 6 to 10), Ernst et al and this paper. I know that ...

### A few questions regarding the difference between policy iteration and value iteration

The question already has some answer. But I am still finding it quite unclear (also does $\pi(s)$ here mean $q(s,a)$ ?): The few things I do not understand are: Why the difference between 2 ...

### Should the reward or the Q value be clipped for reinforcement learning

When extending reinforcement learning to the continuous states, continuous action case, we must use function approximators (linear or non-linear) to approximate the Q-value. It is well known that non-...

### In reinforcement learning, Is the optimal value (V*) corresponding to performing the best action in a given state?

it seems I am a little confused about the optimal value (V*) and optimal action-value (Q*) in reinforcement learning and just want some clarity because some blogs I read on Medium and GitHub are ...

### Q Learning for FrozenLake environment not converging to V* values from Value Iteration

I am trying to learn tabular Q learning, value iteration using the classical algorithms (no neural networks) by using a table of states and actions. I was trying it out on FrozenLake environment in ...

### Can I have different rewards for a single action based on which state it transitions to?

I am working on an MDP where there are four states and ten actions. I am supposed to derive the optimal policy to reach the desired state. At any state, a particular action can take you to any of the ...
