WebBig theta is mainly used when the value of worst-case and the best-case is same. It is the formal way to express both the upper bound and lower bound of an algorithm running time. Let's understand the big theta notation mathematically: Let f(n) and g(n) be the functions of n where n is the steps required to execute the program then: f(n)= θg(n) WebSo this would not affect the Big-Theta running time of the algorithm.

WebFeb 24, 2016 · The equation is read, "f of n is theta g of n". Formal Definition: f(n) = Θ (g(n)) means there are positive constants c 1, c 2, and k, such that 0 ≤ c 1 g(n) ≤ f(n) ≤ c 2 g(n) for all n ≥ k. The values of c 1, c 2, and k must be fixed for the function f and must not depend on n. Also known as asymptotically tight bound, theta.
