The gambler’s ruin problem for a Markov chain related to the Bessel process. Author links open overlay panel Mario Lefebvre. Show more. Share. Abstract. We consider a Markov chain for which the probability of moving from n to n + 1 depends on n. We calculate the probability that the chain reaches N before 0, as well as the average In this paper we present closed-form formulas for the solutions of the gambler's ruin problem for a finite Markov chain where probabilities of winning or losing a particular game depending on the amount of the current fortune, from probability boundary conditions' viewpoint, and provide some very simple closed forms which immediately lead to exact and explicit formulas for some special cases A Markov chain-gambler's ruin problem in the case that the probabilities of winning/ losing a particular game depend on the amount of the current fortune with ties allowed is considered. Closed Thus the gambler’s ruin problem can be viewed as a special case of a first passage time problem: Compute the probability that a Markov chain, initially in state i, hits state j 1 before state j 2. 1There are three communication classes: C 1 = {0 }, C 2 1,...,N − 3 N . 1 and 3 are recurrent whereas C 2 is transient. 4 Markov chain application Gambler's Ruin Problem.

Thanks a lot. . markov-chains 4 Random Walks Note that the last expression is even independent of n. It is also exponentially small in m. If p = 9/19 in our earlier example, then p/(1−p) = 9/10, and for any n, if m = 100 dollars, In this paper we present closed-form formulas for the solutions of the gambler’s ruin problem for a finite Markov chain where probabilities of winning or losing a particular game depending on the amount of the current fortune, from probability boundary conditions’ viewpoint, and provide some very simple closed forms which immediately lead to exact and explicit formulas for some special The derivation of this recursion is as follows: If 1 = 1, then the gambler’s total fortune increases to X 1 = i+1 and so by the Markov property the gambler will now win with probability P i+1. Similarly, if 1 = 1, then the gambler’s fortune decreases to X 1 = i 1 and so by the Markov property the gambler will now win with probability P i 1 A Markov chain-gambler's ruin problem in the case that the probabilities of winning/ losing a particular game depend on the amount of the current fortune with ties allowed is considered. Markov Chains • A Markov chain is a process that evolves from state to state at random. • The probabilities of moving to a state are determined solely by the current state. • Hence, Markov chains are “memoryless” processes. Example: Gambler’s Ruin • p. 444 in the textbook: • You have $1. You play a game of luck,
