30 | 30 | Jaccia has the property that, when started from this condition (entire |

31 | 31 | maze filled with slime cells), the automaton will eventually reach a |

32 | fixed point (steady state) which contains all possible paths from food | |

33 | to food. | |

32 | fixed point (steady state) which contains all possible orthogonal paths | |

33 | from food to food. (Orthogonal paths means, a diagonal isn't considered | |

34 | a path.) | |

34 | 35 | |

35 | 36 | Jacciata is similar, but has the property that when it reaches a fixed |

36 | 37 | point, it will contain the *shortest* path from food to food, if such a |

37 | 38 | path exists and is unique. If no such path exists, or is not unique, the |

38 | 39 | result is undefined. It is otherwise similar to Jaccia. |

40 | The behaviour of both automata is also undefined if the slime | |

41 | configurations are not orthogonal (that is, if there are any diagonal | |

42 | slime paths.) | |

47 | Both Jaccia and Jacciata are defined in ALPACA v0.94. Jaccia is defined | |

44 | Both Jaccia and Jacciata are defined in ALPACA v1.0. Jaccia is defined | |

48 | 45 | in the file `jaccia.alp` and Jacciata in `jacciata.alp`. The ALPACA |

49 | 46 | definition is authoritative; what is given here is merely advisory. |

70 | 67 | exploratory shoot that looks for solutions, and so on. It could probably |

71 | 68 | be made more elegant with some work. |

73 | The definition of these automata in ALPACA suggests some possible | |

74 | improvements to that meta-language, particularly the definition of | |

70 | [New in 1.1] The definition of these automata in ALPACA 0.94 suggested some | |

71 | possible improvements to ALPACA, particularly the definition of | |

75 | 72 | neighbourhoods different from the assumed von Neumann neighbourhood, and |

76 | their use in the count operator. | |

73 | their use in the count operator. The Jaccia and Jacciata descriptions were | |

74 | rewritten in ALPACA 1.0, and do now take advantage of these features in order | |

75 | to be written more succinctly. | |

78 | 77 | Happy intelligence! Such as it is. |
