How do O and Ω relate to worst and best case?
55 Landau notation denotes asymptotic bounds on functions. See here for an explanation of the differences among O O, Ω Ω and Θ Θ. Worst-, best-, average or you-name-it-case time …
When is a bound asymptotically tight? - Computer Science Stack …
What does it mean that the bound $2n^2 = O(n^2)$ is asymptotically tight while $2n = O(n^2)$ is not? We use the o-notation to denote an upper bound that is not asymptotically tight. The …
What is an asymptotically tight upper bound?
Dec 20, 2013 · From what I have learned asymptotically tight bound means that it is bound from above and below as in theta notation. But what does asymptotically tight upper bound mean …

Jan 25, 2018 · (The asymptotic complexity of the worst case is Θ(n) Θ (n), though) For more reading on bounds with Landau ('big O O ') notation, see the reference question How does …
Big-O complexity of sqrt(n) - Computer Science Stack Exchange
Sep 6, 2016 · It asks me to rank functions by asymptotic complexity and I want to understand how they should be reduced rather than just guessing. The question is to reduce this to big-O …
Calculator for time complexity of recursive functions
Jan 30, 2021 · Is there an online tool that returns the time complexity of recursion functions? For instance, when I enter T(n) = T(n/2) + n T (n) = T (n / 2) + n, I'd like to get Θ(n) Θ (n). I tried …
