The following is taken from the prefix of this book: "We believe that mathematicians get more excitement by doing the entire job of proving the existence of solutions and then constructing them by themselves than they do by relying on the computer as a substantial partner in the undertaking. Still, ambitious experts in artificial intelligence are telling us that it will not be long before computers will be doing all that we do, better and faster." It continues: " We hope this book will continue to evoke interest in the four color problem, in its computer aided solution, and perhaps in finding an alternative way to prove it. By the way, a natural follow up would be a four color algorithm." A very interesting book and affordably priced.
