The concept of the Markov chain of order L, which we essentially owe to the Russian mathematician Andrej Andreevic Markov (1907), has two drawbacks. First, the number of parameters of the model grows exponentially with the order L of the chain. This brings about computational and storage problems during implementation, including for limited memory length L.
