A readable-online version of the paper (no download, unless you want a Word copy) https://app.box.com/s/4plplfbrhwr9qflosp8tir00r0pf1467
You can also find the paper here, but you have to download it to read it: https://github.com/johnvlilley/Stateless-Computer
I suggest you start with the simple version of the calculator that does just add and subtract: https://github.com/johnvlilley/Stateless-Computer/blob/master/calculator_simple.cfg
And the complex calculator has much better inline commenting: https://github.com/johnvlilley/Stateless-Computer/blob/master/calculator_complex.cfg
I am interested in taking some of the logic, perhaps the most complicated part - the grenade throwing script, and visually re-creating it in Minecraft. This part of the logic performs the permutations of a math question I came up with and was answered by using the ancient Chinese Pascal's Triangle in a new way. It is similar to the question of how many combinations of 4 hats on 4 pegs you can have, and I just had to count the pegs as part of the permutation where they did not.
I desperately need help writing the paper, it is obvious I never have written one before. I can't offer any money, because I plan to put this in the public domain. I will certainly give credit where credit is due, though. Please contact me at [email protected] or the more reliable [email protected]
