This book contains programming experiments that are designed to reinforce the learning of discrete mathematics, logic, and computability. It is the outgrowth of the experimental portion of a one-year course in discrete structures, logic, and computability for sophomores at Portland State University. The course has evolved over the last ten years from a standard course into a course that uses programming experiments as part of the required activity. Most of the experiments are short and to the point, just like traditional homework problems, so that they reflect the daily classroom work. The experiments in the book are organized to accompany the material in Discrete Structures, Logic, and Computability, Second Edition, by James L. Hein.
