Chapter 1. Problem Solving
What Is an Algorithm?
Explaining how an algorithm works is like telling a story. Each algorithm introduces a novel concept or innovation that improves upon ordinary solutions. In this chapter I explore several solutions to a simple problem to explain the factors that affect an algorithm’s performance. Along the way I introduce techniques used to analyze an algorithm’s performance independent of its implementation, though I will always provide empirical evidence from actual implementations.
Note
An algorithm is a step-by-step problem-solving method implemented as a computer program that returns a correct result in a predictable amount of time. The study of algorithms is concerned with both correctness (will this algorithm work for all input?) and performance (is this the most efficient way to solve this problem?).
