Synopsis

How Hansel and Gretel, Sherlock Holmes, the movie Groundhog Day, Harry Potter, and other familiar stories illustrate the concepts of computing.

Picture a computer scientist, staring at a screen and clicking away frantically on a keyboard, hacking into a system, or perhaps developing an app. Now delete that picture. In Once Upon an Algorithm, Martin Erwig explains computation as something that takes place beyond electronic computers, and computer science as the study of systematic problem solving. Erwig points out that many daily activities involve problem solving. Getting up in the morning, for example: You get up, take a shower, get dressed, eat breakfast. This simple daily routine solves a recurring problem through a series of well-defined steps. In computer science, such a routine is called an algorithm.

Erwig illustrates a series of concepts in computing with examples from daily life and familiar stories. Hansel and Gretel, for example, execute an algorithm to get home from the forest. The movie Groundhog Day illustrates the problem of unsolvability; Sherlock Holmes manipulates data structures when solving a crime; the magic in Harry Potter's world is understood through types and abstraction; and Indiana Jones demonstrates the complexity of searching. Along the way, Erwig also discusses representations and different ways to organize data; "intractable" problems; language, syntax, and ambiguity; control structures, loops, and the halting problem; different forms of recursion; and rules for finding errors in algorithms.

This engaging book explains computation accessibly and shows its relevance to daily life. Something to think about next time we execute the algorithm of getting up in the morning.

Goodreads review by Brian on September 30, 2017

I've been itching to start reading this book for some time, as the premise was so intriguing - to inform the reader about computer science and algorithms using stories as analogies to understand the process. This is exactly what Martin Erwig does, starting (as the cover suggests) with Hansel and Gret......more

Goodreads review by Julie on February 03, 2019

A bit torn over how many stars to give. On the one hand, the concept is great and it is mostly very well executed. The breadth of material covered here and the way it is all brought together in the final chapter is astonishing, and most of the time the explanations are clear and often memorable. Pre......more

Very interesting and adorable intro to computer science.......more

Goodreads review by Rick on October 29, 2019

The book is laid out systematically into Algorithms and Languages. It follows a storytelling way of explaining important concepts in Computer Science. Part One covers -- Algorithms: Where you'll take a tour of Computation, Data Structures and Problem Solving. Part Two covers -- Languages: Where you'......more

Goodreads review by Adarsh on December 28, 2017

The idea behind Once Upon an Algorithm - How Stories Explain Computing -- to explain algorithms, data structures, and computing, in general, using popular stories -- is commendable. However, I feel Martin Erwig might not have met his objectives completely through this book. I worked as a programmer......more
