Consider a CTMC with the embedded discrete-time transition probability matrix and holding time … WebApr 25, 2024 · A Markov chain is a discrete-valued Markov process. Discrete-valued means that the state space of possible values of the Markov chain is finite or countable. A Markov process is basically a stochastic process in which the past history of the process is irrelevant if you know the current system state.
