I recently read Talwalkar’s book on game theory and I enjoy his YouTube channel “Mind Your Decisions”. There are 75 problems in this book equally divided into 3 chapters and a solution immediately follows each problem. Chapter 1 is entitled “Counting And Geometry Problems”. This was by far the most enjoyable chapter. The problems were not simple, but they were still accessible. Many did not require math at all, just a willingness to think outside the box. My favorite problem from this chapter is posed at the end of this review and I invite you to give it a try. Chapter 2 is entitled “Probability Problems”. I was able to hang in there for the first few problems but quickly fell off the merry-go-round. For the tougher problems that I did not know how to solve, I still read through the solutions in an attempt the learn something new. Some of the explanations left me scratching my head. The third chapter was entitled “Strategy And Game Theory Problems”. Several of the examples in this section also appeared in Talwalkar’s book on game theory. Having already decided I was not keen on that branch of mathematics I found this chapter was rather tedious – like being forced to re-watch a movie I didn’t particularly enjoy the first time. Now for my favorite riddle from Chapter 1. I am paraphrasing to save space. A 65-floor building has an elevator with 2 buttons: “Up 8 Floors” and “Down 11 Floors”. A button only works if there are enough floors to complete its mission. For example, the elevator will not move if you are on the 7th floor press “Down 11 Floors”. Question 1: If you are currently on the first floor, is it possible to reach every floor in the building? Question 2: If you are currently on first floor, how many button presses are required to reach the 60th floor? This is a nice book for someone who likes probability and game theory. I could have used more questions like those found in chapter 1.
