From Wikipedia:

A Markov chain (discrete-time Markov chain or DTMC[1]), named after Andrey Markov, is a random process that undergoes transitions from one state to another on a state space.

Coincidentally,

A maquette (French word for scale model, sometimes referred to by the Italian names plastico or modello) is a small scale model or rough draft of an unfinished sculpture.
