Web2 Handout 7: Problem Set 1 Solutions (a) f(n) = O(g(n)) and g(n) = O(f(n)) implies that f(n) = (g(n)). Solution: This Statement is True. Since f(n) = O(g(n)), then there exists an n0 and a csuch that for all n √ n0, f(n) ← Similarly, since g(n) = O(f(n)), there exists an n WebFor any f,g: N->R*, if f (n) = O (g (n)) then 2^ (f (n) = O (2^g (n)) (1) We can disprove (1) by finding a counter-example. Suppose (1) is true -> by Big-O definition, there exists c>0 and integer m >= 0 such that: 2^f (n) <= c2^g (n) , for all n >= m (2) Select f (n) = 2n, g (n) = n, we also have f (n) = O (g (n)), apply them to (2).

WebHeat exchangers with annular finned-tube type and partially wetted condition are utilized widely in engineering systems, such as air-conditioning systems and refrigeration systems. In addition, the physical properties of fin materials should be considered as functions of temperature in reality and thus become a non-linear problem. Based on the above two … WebProve or disprove. - Mathematics Stack Exchange. f ( n) = Θ ( f ( n / 2)). Prove or disprove. I am trying to prove that the statement f ( n) = Θ ( f ( n / 2)) is true. This is what I have so far. I am not sure it is correct. Assume f ( n) = Θ ( f ( n 2)). Then f ( n) = O ( f ( n 2)) and f ( n) = Ω ( f ( n 2)).
WebMar 30, 2012 · Then 2^g(n) also has a restricted subsequence, but 2^f(n) is constant 1 after some point. There is no n0 so g(n) > 0 for all n > n0: 2^g(n) < 1 if g(n) < 0, so g(n) has a restricted subsequence meaning o(2^g(n)) consists only of functions that are constant 0 after some n or converge to 0.
WebJan 20, 2016 · We actually only need f(n) to be nonzero, since it's the only one in the denominator. As for why g(n) / f(n) tends toward zero in the limit, you can actually show using the formal definition of a limit to infinity (the ε-n one) that if g(n) = o(f(n)), then lim g(n) / f(n) = 0 as n tends toward infinity. 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
