Algorithms to Live By: The Computer Science of Human Decisions.

ChatGPT general & 2 detailed reviews. First detailed review stopped at chapter 7, then didn't cover all chapters, for some reason. 

"Algorithms to Live By" is a fascinating book that explores how ideas from computer science can be applied to everyday life. The authors, Brian Christian and Tom Griffiths, provide insights into how we can use algorithms to solve real-world problems more effectively and make better decisions.

The book is divided into twelve chapters, each focusing on a different algorithm and its application to everyday life. The algorithms covered include sorting, caching, scheduling, prediction, randomness, game theory, and more. The authors explain these algorithms in a way that is accessible to readers without a technical background, using real-world examples to illustrate their points.

One of the key strengths of the book is how the authors relate these algorithms to human behavior and decision-making. For example, they explore the benefits of procrastination (using the "optimal stopping" algorithm), how we can use the "explore/exploit" algorithm to decide between trying new things or sticking with what we know, and how the "Bayesian updating" algorithm can help us revise our beliefs based on new evidence.

Overall, "Algorithms to Live By" is an engaging and thought-provoking book that provides valuable insights into how computer science can help us navigate the complexities of everyday life. Whether you're a computer science enthusiast or simply interested in improving your decision-making skills, this book is definitely worth a read.
