Intuitively, it's sort of a way to frame RL tasks such that we can solve them in a "principled" manner. We will go into the specifics throughout this tutorial. The key in MDPs is the Markov Property. Essentially the future depends on the present and not the past.

WebbPython Markov Chain Packages Markov Chains are probabilistic processes which depend only on the previous state and not on the complete history. One common example is a very simple weather model: Either it is a rainy day (R) or a sunny day (S). On sunny days you have a probability of 0.8 that the next day will be sunny, too.
