NOTES on the exercises

The exercises in this set of books has been designed for self-study as well as classroom study. It is difficult, if isn't impossible, for anyone to learn a subject purely by reading about it, without applying the Informa tion to specific problems and thereby being encouraged to think on what's has been read. Furthermore, we all learn best the things and we have discovered for ourselves. Therefor the exercises form a major part of; A definite attempt have been made to keep them as informative as possible and to select problems that is enjoyable as well As instructive.

In many books, easy exercises is found mixed randomly among extremely difficult ones. This was sometimes unfortunate because readers like to know in advance what long a problem ought to take--otherwise they m Ay just skip over all the problems. A classic example of such a situation is the book Dynamic programming by Richard Bellman; This was an important, pioneering work in which a group of problems are collected together at the end of some chapters under The heading "exercises and problems," with extremely trivial questions appearing in the midst of deep, unsolved Problems. It's rumored that someone once asked Dr. Bellman how-to-tell the exercises-apart from the the problems, and he repli Ed, "If You can solve it, it's an exercise; Otherwise it ' s a problem. "
