Yeah, it’s a good book with great visuals. The author, Jamis Buck, actually lives in my town. He visited my University and gave a lecture on generating a Zelda like over-world by using maze algorithms. It was an interesting application. Jamis writes in Ruby and helped with Ruby on Rails. He has a good blog too [1].
bad taste, you give a link to 10 page version and tell people to look at p. 36
Dijkstra’s algorithm is on page 36 and explained in 8 paragrpahs.
