The study of random combinatorial structures and algorithms has been an active area of modern research. Deterministic algorithms may tend to behave differently on different inputs. For analysis one assumes some reasonable probability distribution on input instances to an algorithm as a way of understanding its ``typical behavior." Experience in the field shows that it is often hard to work with exact models, where on the other hand one can say something meaningful and precise on the typical ``asymptotic" behavior of the algorithm operates massive data sets.
