Walnut is computer software, written in Java, that implements an algorithm to decide the truth of first-order logic statements in an extension of Presburger arithmetic known as Buchi arithmetic. It can be used to prove a wide variety of results in combinatorics on words and number theory. In this course we will give an introduction to the theory behind Walnut, examples of the types of results that can be proved with it, and exercises for participants to get some hands-on training on how to use Walnut.[-]
