-The Jaccia and Jacciata Cellular Automata
-=========================================
-
-Overview
---------
-
-Jaccia and Jacciata are cellular automata inspired by the Announcement of
-[Scientific Proof that Slime Molds are Intelligent Maze Solvers][].
-
-Basically, the slime mold solves the maze by:
-
--   initially being everywhere in the maze
--   there being food at the entrance and exit of the maze
--   minimizing its surface area by retreating from anywhere it can't get
-    food.
-
-Jaccia operates the same way. In the Jaccia automaton, slime cells
-survive if they have immediate neighbours in at least two cardinal
-directions that provide sustenance, i.e. are either food or other slime
-cells. The result is the same: paths of slime cells that lead down dead
-ends have one end which provides no sustenance and dies off. Eventually,
-only paths of slime cells that reach from food to food (or uninterrupted
-circular paths of slime cells) remain. Jacciata is a more involved
-automaton which finds only the shortest path.

-Properties
-----------
-
-Jaccia has the property that, when started from this condition (entire
-maze filled with slime cells), the automaton will eventually reach a
-fixed point (steady state) which contains all possible orthogonal paths
-from food to food.  (Orthogonal paths means, a diagonal isn't considered
-a path.)
-
-Jacciata is similar, but has the property that when it reaches a fixed
-point, it will contain the *shortest* path from food to food, if such a
-path exists and is unique. If no such path exists, or is not unique, the
-result is undefined. It is otherwise similar to Jaccia.
-
-Definition
-----------
-
-Both Jaccia and Jacciata are defined in ALPACA v1.0. Jaccia is defined
-in the file `jaccia.alp` and Jacciata in `jacciata.alp`. The ALPACA
-definition is authoritative; what is given here is merely advisory.
-
-Both automata use basically the same set of symbols. An initial Jaccia
-playfield generally serves as an initial Jacciata playfield with the
-same kind of solution.
-
--   ` ` - empty space
--   `#` - wall (purely decorative)
--   `%` - slime mold
--   `F` - food
--   `S` - "start" food (needed in Jacciata, optional in Jaccia)
--   `-` - exploratory head (Jacciata only)
--   `?` - exploratory body (Jacciata only)
--   `@` - solved (Jacciata only)
-
-Discussion
-----------
-
-Jacciata's definition is not very elegant, especially when compared to
-Jaccia. In order for it to work, the two sources of food need to be
-labelled differently (`S` and `F`), there needs to be a "head" of an
-exploratory shoot that looks for solutions, and so on. It could probably
-be made more elegant with some work.
-
-[New in 1.1] The definition of these automata in ALPACA 0.94 suggested some
-possible improvements to ALPACA, particularly the definition of
-neighbourhoods different from the assumed von Neumann neighbourhood, and
-their use in the count operator.  The Jaccia and Jacciata descriptions were
-rewritten in ALPACA 1.0, and do now take advantage of these features in order
-to be written more succinctly.
-
-Happy intelligence! Such as it is.
