WebFormal definition [ edit] A Markov chain is an absorbing chain if [1] [2] there is at least one absorbing state and. it is possible to go from any state to at least one absorbing state in a finite number of steps. In an absorbing Markov chain, a … A Markov chain or Markov process is a stochastic model describing a sequence of possible events in which the probability of each event depends only on the state attained in the previous event. Informally, this may be thought of as, "What happens next depends only on the state of affairs now." A … Meer weergeven Definition A Markov process is a stochastic process that satisfies the Markov property (sometimes characterized as "memorylessness").
