WebbWe have already had a recurrence relation of an algorithm, which is T (n) = 4T (n/2) + n2 log n. (a) (5 points) Solve this recurrence relation, i.e., express it as T (n) = O (f (n)), by using the iteration method. Answer: (b) (5 points) Prove, by using mathematical induction, that the iteration rule you have observed in 4 (a) is Webb2 feb. 2024 · We begin by guessing that this recurrence has an upper bound in O ( n 2) . To be more precise, assume that T ( n) ≤ n 2. We prove this guess is correct by induction. In this proof, we assume that n is a power of two, to make the calculations easy. For the base case, T ( 2) = 1 ≤ 2 2 .

WebbContinuing with the previous derivation we get the following since k = log2 n : = 2k T (n/2k) + k n = 2log2 n T (1) + (log2n) n = n + n log2 n [remember that T (1) = 1] = O (n log n) So we've solved the recurrence relation and its solution is what we "knew" it would be. WebbRecurrence Relations T(n) = T(n=2) + 1 is an example of a recurrence relation A Recurrence Relation is any equation for a function T, where T appears on both the left and right sides of the equation.
