Резюме:<p>Expectation-based probabilistic predicate transformers [15] provide a logic for probabilistic sequential programs, giving access to expressions such as &amp;apos;the probability that predicate <em>A</em> is achieved finally&amp;apos;. Using expectations more generally however, we can express calculus formulae for the expected path-length of a computation tree. Moreover within an expectation-based calculus such efficiency measures and more conventional (but probabilistic) temporal operators [14] can be related.</p>
