In the world of complex systems, simplicity can be surprisingly powerful. Simple models allow us to capture the essence of a system evolution by ignoring details that are unnecessary to produce useful results. The Markov chain is a great example of such a model: by focusing on the probabilities of transitioning between different states, it enables us to uncover valuable insights and make informed decisions. Embrace the elegance of the Markov chain as you explore its widespread applications, from artificial intelligence, science and economics to the design of board games and modern video games.
