A state S is an absorbing state in a Markov chain in the transition matrix if. The row for state S has one 1 and all other entries are 0. AND. The entry that is 1 is on the main diagonal (row = column for that entry), indicating that we can never leave that state once it is entered.

WebbA Markov chain is a mathematical system that experiences transitions from one state to another according to certain probabilistic rules. The defining characteristic of a Markov chain is that no matter how the process arrived at its present state, the possible future states are fixed. <1, we can always reach any state from any other state, doing so step-by-step, using the fact ...
