Solve the recurrence relation using a recursion tree AND substitution method: T(n) = 2T(n - 1) + 10n.
Algorithm Question: Problem 3. Solve the recurrence relation T(n) = 2T(n/2) + lg n, T(1) 0.
Question 1 (4 points) Answer the following questions. a. Draw a recursion tree for the recurrence T(n) T(an) + T(1- a)n cn, where 0 α < 1 and c > 0 are constants. Draw the nodes at three levels, i.e., level 0, 1, and 2 (root node is level 0).
1. Solve the recurrence relation T(n) = 2T(n/2) + n, T(1) = 1 and prove your result is correct by induction. What is the order of growth? 2. I will give you a shortcut for solving recurrence relations like the previous problem called the Master Theorem. Suppose T(n) = aT(n/b) + f(n) where f(n) = Θ(n d ) with d≥0. Then T(n) is: • Θ(n d ) if a < bd • Θ(n d lg n) if a = b...
draw the first 3 levels of a recursion tree for the recurrence T(n) = 4T(n/2) + n. How many levels does it have? Find a summation for the running time and solve for it.
Solve the recurrence relation T(n) = 2T(n / 2) + 3n where T(1) = 1 and k n = 2 for a nonnegative integer k. Your answer should be a precise function of n in closed form. An asymptotic answer is not acceptable. Justify your solution.
6. Consider the recurrence relation T(n) = 2T(n-1) + 5 for integers n 1 and T(O) = 0. Find a closed-form solution Using induction, prove your solution correct for all integers n 20.
Consider the recurrence T (n) = 3 · T (n/2) + n. • Use the recursion tree method to guess an asymptotic upper bound for T(n). Show your work. • Prove the correctness of your guess by induction. Assume that values of n are powers of 2.
