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].
I find Floyd–Warshall algorithm much more facinating. It took me almost 25 years to realize that it was different from the algorithm that I had deviced myself for solving the problem.
Dijkstra's algorithm seems rather obvious to me, as I discovered it myself after I head the problem description. A note in my diary seems to imply that I implemented it in LISP.
This is a pretty good explanation. Putting nodes in a priority queue at each stage is the trick here. I wish I had this explained in such a simple manner earlier.
Dijkstra’s algorithm is on page 36 and explained in 8 paragrpahs.
