I am looking for references on mazes or labyrinths. I prefer books, but research articles are welcome, too. I am looking for the mathematical point of view of mazes, not their history or development.
Any book that has a chapter about mazes is welcome, too (for example, a graph theory book with a chapter about mazes).
So far, I've found Mazes for Programmers, which talks about how to code mazes.
Some pointers:
