judging an algorithm by its worst expected cost under small random perturbations of inputs, explaining why some worst-case slow methods run fast in practice.

In algorithms, smoothed analysis refers to judging an algorithm by its worst expected cost under small random perturbations of inputs, explaining why some worst-case slow methods run fast in practice. This meaning comes from Spielman (2004) in Journal of the ACM.[1]
