Software Engineering Stack Exchange is a question and answer site for professionals, academics, and students working within the systems development life cycle. In this case, it is safer to assume that the only inputs are those that cause the most amount of grief to your algorithm. Big-omega Given a function f(n) that describes the amount of resources (CPU time, RAM, disk space, etc) consumed by an algorithm when applied to an input of size of n, we define up to three asymptotic notations for describing its performance for large n.
