Today we consider ways in which one might choose between different algorithms that purport to solve the same problem. We look at a mathematical notation, Big O, that lets us describe the space or time requirements of an algorithm.

Question 9 for today: Suppose you've been given two sets of instructions that solve the same problem. What criteria might you use to determine whether one is better than the other?

Question 10 for Tuesday: Describe how to put a pile of books in alphabetical order by author.




Three Smallest Algorithms
