Analyze and prove the running time of the recursive formula T(n) = n2 + 2T(n/2). (hint- first prove that it is O(n2 logn). Next see if you could improve your answer.
We used the recursion tree method to analyze the running time of MergeSort. Use this method to analyze each one of the following recursive formulas, and obtain its solution. Assume T(n) = 1 when n ≤ 1.

Problem 5: Recurrence relations and detailed analysis of recursive algorithm efficiency g(n: non-negative integer)  
Problem 5: Recurrence relations and detailed analysis of recursive algorithm efficiency g(n: non-negative integer) 1. if n ≤ 1 then return n 2. else return (5 * g(n─1) ─ 6 * g(n─2)) MergeSort divides the array to be sorted into two equal halves, calls itself recursively on each half to sort that subarray, and then calls the Merge algorithm to merge the two sorted halves in linear time. This leads to its two recurrence relations T(n)=2T(n/2)+cn, n>1;...

Let T(n) denote the worst case running time of an algorithm when its input has size n. In divide and conquer algorithms, T(n) is often expressed using a recursion. Hence, expressing T(n) in terms of the big-Oh notation requires a bit of work. There are many ways of determining the growth rate of T(n). In class, I’ve shown you how to do it by drawing the recursion tree. Here are the steps: (1) draw the recursion tree out, (2) determine...

Weird recursion tree analysis. Suppose we have an algorithm that on problems of size n, recursively solves two problems of size n/2, with a “local running time” bounded by t(n) for some function t(n). That is, the algorithm’s total running time T(n) satisfies the recurrence relation T(n) ≤ 2T(n/2) + t(n). For simplicity, assume that n is a power of 2. Prove the following using a recursion tree analysis (a) If t(n) = O(n log n), then T(n) = O(n(log...
