Preface
The problems in the book, "Elements of Information Theory", were chosen from the problems used during the course at Stanford. Most of the solutions here were prepared by the graders and instructors of the course. We would particularly like to thank Prof. John Gill, David Evans, Jim Roche and Laura Ekroot for their help in preparing these solutions.
Most of the problems in the book are straightforward, and we have included hints in the problem statement for the difficult problems. In some cases, the solutions include extramaterial of interest (for example, the problem on coin weighing on Pg. 23 and the problem on gambling with unfair odds on Pg 90). Exceptions to the general simplicity of the problemsinclude Problems 2.4, 6.7 and 6.8 (both of which require some numerical optimization on a computer) and 13.10.
We will take this opportunity to point out a few errors in the first printing of the book.
In Problem 2.35, the problem should read "increases"rather than "decreases". In problem
4.7, the assumption of stationarity is not required. In problem 4.14(b), the "="should be replaced by "<". In problem 4.14(c), the process should be stationary and ergodic. In problem 7.6, the problem should only ask to show that the output entropy of the computer is infinite, not that it is equal to the input entropy. More detailed explanations of these errors can be found in the appropriate solutions.
