My Students Are Adding To An Online Textbook

My teaching philosophy is not to waste student time. The last two times I taught my undergrad AI class I have instructed them to contribute to the online AI textbook at

They had to describe a search method in AI. Now most of the main methods are covered. With hope, in ten years or so I won't even need them to buy a textbook.

Below are some of the wikibook chapters my students have made. Note that since anyone can edit the wikibook, they might have been changed since I posted this.

Bidirectional Search
