Is your light still on? Reading notes 1

"Your light is still on" this book, if starting from preface, then Zang's preface has let me from the first impression of the content of this to be told.

This is a book full of problems, but also a book on how to solve problems, it will tell us a kind of thinking, a problem-solving approach, rather than a specific solution to the problem. The author's ability to tell is still very strong, because he tells a story, will attract me from different angles to think about the problem, in the previous reading, the first story let me quite touched.

The first story tells the story of an elevator use, when I saw the elevator scheduling problems, my first reaction and most people, I am trying to think of a variety of solutions to the problem of elevator scheduling is gone.
