Let’s say we have the recurrence relation given below. T(n) = 2 * T(n-1) + c1, (n > 1) T(1) = 1. We know that the answer is probably T(N) = O(2 n). The observation that we are almost doubling the number of O(1) operations for a constant decrease in n leads to the guess.

WebMay 26, 2024 · The Master Theorem lets us solve recurrences of the following form where a > 0 and b > 1: T (n) = aT (n/b) + f(n) Let's define some of those variables and use the recurrence for Merge Sort as an example: T (n) = 2T (n/2) + n. n - The size of the problem. For Merge Sort for example, n would be the length of the list being sorted.
