WebOne popular notion of optimality is worst-case running time, which is what you describe: An algorithm for solving a problem P is asymptotically optimal with respect to worst-case running time if it runs in time T ( n), and any algorithm for P runs in time Ω ( T ( n)). In fact, this notion is ambiguous, since it's not clear what the parameter n is. trusthorpe lincsWebFeb 25, 2024 · Pareto-optimality, a concept of efficiency used in the social sciences, including economics and political science, named for the Italian sociologist Vilfredo Pareto.
