Computer Science 101 A Survey of Computer Science

Computer Science 101 A Survey of Computer Science. Efficiency of Divide and Conquer. Background - Logarithms (Base 2). Definition. The logarithm to base 2 of n is that number k such that 2 k =n. Example: 2 5 =32 so Lg(32)=5.

Lecture 12: Lower bounds

Lecture 12: Lower bounds. By "lower bounds" here we mean a lower bound on the complexity of a problem , not an algorithm. Basically we need to prove that no algorithm, no matter how complicated or clever, can do better than our bound. This is often hard!

Pass The Buck

Rules: You are given a problem to solve (of size n) You have a neighbor who is almost as smart as you are You want to do as little work as possible The idea is to take your problem, make it into a smaller problem (size < n) , and give it to your neighbor. Pass The Buck.
