Reasoning Realm

This is an implementation of cellular automata in HTML5 with javascript, in development since 2016-03-03. It originated as an attempt to re-implement Jack Eisenmann's "Logic Land" cellular automaton better than he did, but it grew far beyond that and became capable of running other rules. As such, "Reasoning Realm" was named after it; other names with this structure include "Intelligence Island", "Deduction Dimension", and "Smartness Sphere". Dan came up with the last two. The source code of this program is over 2000 lines, and it's all just one .html file. Reasoning Realm can currently run Lifelike CA, Generations rules, cylic cellular automata, and generalised wire automata (including Wireworld) with moore, JvN, and hexagonal neighbourhoods, Logic Land, Rychládrát, and LifeHistory.

I declare this to be free software. Feel free to reverse engineer it, distribute it, modify it, distribute modifed versions of it, etc (as if anyone cares enough). The source code is this file itself.

Credit goes to BLAH (ME) for being, like, really smart, Jack Eisenmann for inspiration and Logic Land savecodes (the functions to handle that were taken straight from his code with his permission), and dan.

Changelog

0.3.1

2018-04-26

The day is 2017-12-08, and I've decided to go back and fix some things after about 13 months of inactivity.

... The month is 2018-04. I'm going back to finish this version now.

• +A snake.
• +Generalised Wire Automata. "WireWorld" and "Bliptile" are interpreted as their equivalent CA in this rulespace; Wire12 and Wire1v, respectively. Sadly, Bliptile used state numbers differently, so Bliptile patterns don't work directly.
• +*-There is now only one set rule button; it automatically detects which of the two supported formats you're using.
• +*Cyclic cellular automata now perceive neighbourhoods correctly. cyclic16 uses the moore neighbourhood, cyclic16v, the von neumann, and cyclic16h, the hexagonal. Does that make grammatical sense? Whatever.
• *Fixed bug where getRLE() would register amount of empty lines above the pattern as one less than it should be.
• *Apparently fixed bug where generations rules with hexagonal neighbourhoods would produce innacurate behaviour while using the sparse algorithm. I never experienced it but I guess it existed.

Todo List

This is a list of easy and difficult goals. Some I will probably never bother to do. They are in no order whatsoever. This list is maintained poorly if at all.

• Add options for colour schemes
• Make the 'close' button in the help menu follow you as you scroll down
• Add support for unbounded grids
• Add support for other geometries, like cylinders, toruses, klein bottles, etc
• Allow multiple worlds loaded at once
• Add undo functionality
• Change the program to use a 1D array because it's probably faster

Bugs:

• The get selection tool is FUBAR.
