# Slides

This page contains slides from David Poole and Alan Mackworth, Artificial Intelligence: foundations of computational agents, 2nd edition, Cambridge University Press, 2017.

These slides are in PDF format and can be read using the free acrobat reader or with recent versions of Ghostscript. You can get a zip file of the latest distribution of all of the slides that includes the sources. They were written using the LaTeX beamer class. To regenerate them you will also need the figures, and our beamer style file Note that the sources may change frequently.

We have divided the slides roughly into lectures. The division is largely on logical separation, rather than what can be carried out in one say 50 or 90 minute slot. We have found that one lecture here takes between 30 and 100 minutes to explain in class (augmented with class discussion and more detailed examples). These slides may be more terse than some instructors may prefer to put on slides; they need to be augmented with worked out examples, such as those on our online learning resources. There is another collection of slides for a course based on the book that are made available by Giuseppe Carenini.

We haven't attempted to cover every topic in these lectures; rather, we have attempted to give a deeper view of fewer topics. Revising these slides is an ongoing activity; we would appreciate any feedback you would like to give.
