Summary
big_omega_notation gives an asymptotic
lower_bound. f(n) is in Ω(g(n)) if there exist constants c>0 and n0 with f(n) >= c*g(n) for all n >= n0. It captures a
guaranteed_minimum growth_rate in
asymptotic_analysis. Use it to state an algorithm cannot be faster than some function beyond a threshold. Contrast with
big_o_notation (
upper_bound) and
big_theta_notation (
tight_bound). Remember: lower bound, constants, threshold n0, and Ω means at least up to a
constant_factor.
