How to show something is a markov chain
WebEvery Markov chain can be represented as a random walk on a weighted, directed graph. A weighted graph is one where each edge has a positive real number assigned to it, its “weight,” and the random walker chooses an edge from the set of available edges, in … WebDe nition 1.1 A positive recurrent Markov chain with transition matrix P and stationary distribution ˇis called time reversible if the reverse-time stationary Markov chain fX(r) n: n2 Nghas the same distribution as the forward-time stationary Markov chain fX n: n2Ng, that is, if P(r) = P; P i;j(r) = P i;j for all pairs of states i;j ...

WebNov 29, 2024 · To show what a Markov Chain looks like, we can use a digraph, where each node is a state (with a label or associated data), and the weight of the edge that goes from node a to node b is the probability of jumping from state a to state b. Here’s an example, modelling the weather as a Markov Chain. Source http://www.columbia.edu/~ks20/stochastic-I/stochastic-I-MCI.pdf

WebJan 13, 2015 · So you see that you basically can have two steps, first make a structure where you randomly choose a key to start with then take that key and print a random value of that key and continue till you do not have a value or some other condition. If you want you can "seed" a pair of words from a chat input from your key-value structure to have a start.
