We extend qualitative reasoning with estimations of the relative likelihoods of the pos sible qualitative behaviors . We estimate the likelihoods by viewing the dynamics o f a system as a Markov chain over its transition graph. This corresponds to addin g probabilities to each of the transitions. The transition probabilities follow directl y from theoretical considerations in simple cases . In ...
