WebWe need to convert the transition probabilities into transition rates for a continuous-time Markov chain (CTMC). We can assume that the holding times in each state are exponentially distributed with mean 1. Then, the transition rates are equal to the transition probabilities: q_AB = p_AB = 0.3; q_AS = p_AS = 0.7; q_BA = p_BA = 0.6; q_BS = p_BS ...
