What is a Markov Chain?
A Markov chain is a mathematical model used to represent a system that transitions between different states over time. It is a stochastic process, meaning that the next state of the system is determined probabilistically based on its current state and the probabilities of transitioning to each possible state. The key characteristic of a Markov chain is that it has the Markov property, which states that the probability of transitioning to a future state depends only on the current state and not on any past states. Markov chains are widely used in various fields, including physics, biology, economics, and computer science, as they can model a wide range of phenomena that exhibit stochastic behavior.
