<Tom 7> (SPOILER) Oops. Yeah, you're not supposed to be able to get into the bottom until you do more stuff. But the reason you can get in is sorta important to the solution, hmm..
<Joshua Bone> (SPOILER) Added solution "Cook":

<Joshua Bone> (SPOILER) Cook: This one just felt like a cook. I just walked around pressing buttons 'til one appeared that opened the exit, so I held it open with a block and exited. Didn't use the light switch at all.
<Alois> (SPOILER) Added solution "Alois."

Sorry to rob you of your hard-earned satisfaction, Tom...

Double gotcha.

Turing Machine Fri 08 Apr 2005 10:09
<mjn> (SPOILER) Yeah, it's a shame about some of those teleports; I did want to keep it (relatively) small, though.

Perhaps it's a little hard to see, with the gigantic size and all, but almost all of the teleports are predictable, and you can actually observe two-thirds of the program without knowing where any of the teleports go--the green and blue switch blocks in the state area are used to indicate 0/1 (for writing) and L/R, respectively.

(Not that that helps a player who doesn't know how TMs work, I guess...)

I'm glad I resisted the temptation to program this with a busy beaver function, though.

Turing Machine Fri 08 Apr 2005 09:33
<Tom 7> (SPOILER) Given that my solution was 1877 moves and yours was 1875, I'd say this is pretty damn tight.

This is a cool encoding! Although the level is totally easy (turing machines aren't "games" so this isn't a surprise) and kind of repetetive, it does give you time to study what's happening. There are two things that are unfortunate: (1) the tape is finite, so this isn't really a turing machine (but it's clearly not possible to code up any infinite storage in Escape played on a finite map, and probably not possible even on an infinite grid, because of conservation of matter)--it's sort of a turing finite automata. But still, it's easy to see how to generalize to arbitrarily long tape. (2) Because the machine's program is encoded in the destinations of teleports, it makes the "interesting" part of the level essentially hidden from the player. I don't know how you could have gotten around this without making the level much bigger, though.

Anyway, cool!

<Joshua Bone> (SPOILER) As a technological demonstration this is an incredible feat of engineering. The mechanisms all appear to work perfectly. Aside from a triple choice of teleports at the beginning, there does not seem to be any other possible path to take except for the solution route. Extremely tight.
<mjn> From the embedding department: a Turing Machine.

Tape, tape heads, and "motor" on the left; state memory and transition function on the right. This particular machine (which I stole from the Wikipedia article) duplicates a series of 1's. (Solution's a little long, unfortunately, but I thought it'd be nice to have a machine that actually does something, rather than putter around for a few steps and stop abruptly.)

(I'd recommend playing this zoomed-out.)
