CSE 421 Assignment #4
Winter 2006
Due: Thursday, Feb 2, 2006
Reading Assignment: Kleinberg and Tardos Chapter 6.
Problems: (see Grading Guidelines sheet before answering)
-
Suppose T(n) = 8T(n/2) + n2, and T(1) = 0. Prove that
T(n) = O(n3). You may assume that n is a power of 2.
- Suppose T(n) = 7T(n/2) + n2, and T(1) = 0. Show that
T(n) = O(nlg(7)). You may assume that n is a power of 2.
- Give the best asymptotic upper bound you can
for T(n) in each of the following examples. You may assume T(n) is constant for n <= 2.
- T(n) = 5T(n/3) + n.
- T(n) = T(2n/3) + n.
