WebJan 31, 2024 · Let f (n) = 2 and g (n) = 1. Then f (n) = O (g (n)). However, log (f (n)) = 1 and log (g (n))= 0. There is no n0 nor any c such that 1 <= c * 0. EDIT: presumably, statement II is not formatted properly and should read 2^f (n) = O (2^g (n)), which is false if f (n) = 2n and g (n) = n, e.g. Share Improve this answer Follow WebOct 2, 2013 · According to this page: The statement: f (n) + o (f (n)) = theta (f (n)) appears to be true. Where: o = little-O, theta = big theta This does not make intuitive sense to me. We know that o (f (n)) grows asymptotically faster than f (n). How, then could it be upper bounded by f (n) as is implied by big theta? Here is a counter-example:

WebFeb 13, 2016 · If you emanate from the formal definition of Big-ϴ notation, it is quite apparent that this holds. f ∈ ϴ (g (n)) ⇨ For some positive constants c1, c2, and n0, the following holds: c1 · g (n) ≤ f (n) ≤ c2 · g (n) , for all n ≥ n0 (+) Let f (n) be some arbitrary real-valued function. Set g (n) = f (n) and choose, e.g., c1=0.5, c2=2, and n0 = 1. Web1 Answer Sorted by: 9 You are correct. If f ( n) ∈ Θ ( g ( n)), then there are constants c 1, c 2 > 0 such that for large enough n, we have c 1 g ( n) ≤ f ( n) ≤ c 2 g ( n) . But this implies g ( n) ≤ 1 c 1 f ( n) as well as 1 c 2 f ( n) ≤ g ( n), for large enough n. 1 c 2 f ( n) ≤ g ( n) ≤ 1 c 1 f ( n). Therefore, g ( n) ∈ Θ ( f ( n)). Share Cite
