Jamis Buck is very interested in mazes. He even wrote a book about it named "Mazes for programmers"https://www.jamisbuck.org/mazes/It contains algorithms for generating and solving mazeshttps://pragprog.com/titles/jbmaze/mazes-for-programmers/-J. -------- Original message --------From: cody dooderson <d00d3r...@gmail.com> Date: 2/28/21 01:10 (GMT+01:00) To: The Friday Morning Applied Complexity Coffee Group <friam@redfish.com> Subject: Re: [FRIAM] solving mazes I am assuming this is a 2D maze. Wikipedia does a better job at explaining the problems with wall following than I can. If the maze is not simply-connected (i.e. if the start or endpoints are in the center of the structure surrounded by passage loops, or the pathways cross over and under each other and such parts of the solution path are surrounded by passage loops), this method will not reach the goal.On Sat, Feb 27, 2021, 1:48 PM <thompnicks...@gmail.com> wrote:Hi, All,Due to a review I have been working on, I have been dragged back into thinking about maze learning in rats. Any animal I have ever known, when confined, will explore the boundaries of its enclosure. Cows, for instance will beat a path just inside the barbed wire that encloses them. So a maze is not only a series of pathways but it is also an enclosure. If the rat puts his left whisker against the left wall of the maze, he will eventually get to the goal box, right. It works with the Hampton Court Maze. On the second run, he can now use odor cues, such that any time he encounters his own odor both entering and leaving a passage way, he should just skip that passage way. So I am wondering, you topologists (??) out there, how general is the statement, “every maze is an enclosure” and what is the limitation on the idea that any maze can be solved by putting your right or left hand on a wall and continuing to walk until you find the goal or are let out of the maze. Now I should quickly say that rat mazes are usually composed of a series of bifurcating choice points, where the rat can go either left or right. Some choices lead ultimately to dead ends. In sum, a runway in such a maze can go straight, turn R or L without choice or form a T with a right or left choice. My intuition is that no such maze can be designed that does not permit the boundary following strategy.
