What are the similarities between Q-learning and Value Iteration?
Q learning is very similar to value iteration. They are based on the same principles. A key similarity is that both assume a greedy action choice on the bootstrap next state value.
The big difference ...

In Q-learning, Am I the one who will define the way in which actions allow the agent to interact with the environment? And the interactions will vary?
The action space for a reinforcement learning (RL) task is mostly determined by the problem you are applying RL to. As such, you get to define it in the following ways:
By choosing what problem to ...
