Soar is a problem-solving architecture used for cognitive modelling, though it is also often used in writing artificial intelligence (AI) programs.

This document aims to be a self-contained online introductory tutorial of Soar with an emphasis on cognitive modelling. We will pay some heed to the AI and programming aspects of Soar, as we must -- as a cognitive modelling theory Soar proposes that intelligence consists of a set of mechanisms that do not change across tasks, that is, the architecture, and that knowledge of how to perform tasks is also necessary -- hence intelligence has aspects of being programmable. What this means and how we go about doing it with Soar is what this tutorial is all about.

The major difference between this tutorial and other Soar materials and other Web documents, is that it is designed to be used with a running Soar. We have included several simple (and some not so simple) exercises to test and further your understanding while reading the tutorial.

This tutorial when presented 'live', takes about 3.5 hours for the hungry-thirsty material and about 2 hours for the analogy material. You might plan on spending about that time, including some reading, unless you run into problems with getting Soar installed or a silly syntax bug such as forgetting to close a parenthesis.

This version is designed to be used with the Tcl/Tk Soar Interface, version 2.2 or better.

If you have any questions, please email one of us -- FER or RMY (see addresses below).
