As for Life and Wireworld, I've put this in the Games category; but I think it could be better to add a new category like "Cellular automata" and put those tasks in that category (too, and secondary in Games, if one thinks about them as games). --[[User:ShinTakezou|ShinTakezou]] 17:01, 12 July 2010 (UTC)
:They are certainly games. Mathematical games. --[[User:Paddy3118|Paddy3118]] 21:01, 12 July 2010 (UTC)
::: I in general agree, but they are different by [[Bulls and cows]], [[Go Fish]], [[Minesweeper game]], ... Maybe as tasks in this category grow in number, it could become useful to give a more "precise" cathegorization. --[[User:ShinTakezou|ShinTakezou]] 06:26, 13 July 2010 (UTC)
:: I think we usually call those Puzzles on RC. --[[Special:Contributions/76.236.174.54|76.236.174.54]] 21:06, 12 July 2010 (UTC)
: By all means! I'm just fine with MW categories being used as tags. We may need to be a bit selective in which we make direct subcategories of [[:Category:Solutions_by_Programming_Task]], though. --[[Special:Contributions/76.236.174.54|76.236.174.54]] 21:06, 12 July 2010 (UTC)
: Usually CA fall under modeling formalisms and running them is essentially simulation. It would fit in the same category like Monte Carlo Simulation, actually. —[[User:Hypftier|Johannes Rössel]] 10:43, 13 July 2010 (UTC)
:: My original in-editor version of the task's text began with "Simulate a forest fire; as model use ...", ... this task itself is a switch from my first idea of doing a task about the Ising model — I think it will be one of my next new task, if nobody anticipates me. --[[User:ShinTakezou|ShinTakezou]] 12:15, 13 July 2010 (UTC)
==what to call it==
I agree with everything above, fine points, all.
* '''Cellular automata''': very descriptive, but if you don't know what that is... I never would've thought to look under that tag. I know what it is, but I hardly ever use that term, I usually think CA refers to more pure (and esoteric) mathematics.
* '''game''': yes, but only if the program would be very robust in accepting various parameters, such as field size, characters to use, but most of all, the various percentages. Games typically require a goal to reach (in other words, what do you need to do to "win"? Or survive?) More rules could be accepted (fires only burn if the trees are dense enough...).
* '''puzzle''': yes, but only if there is a goal to reach, such as a stable (living) forest.
* '''modeling''': yes, fur shure.
* '''simulation''': yes, as above. "Simulate a forest fire (with tree growth, fires caused by lighnting, ...) sounds the best to be.
Any one name would probably do a disservice in describing/pigeonholing the task. -- [[User:Gerard Schildberger|Gerard Schildberger]] 02:50, 5 April 2012 (UTC)
:CA is actually the most accurate (there's a lot of mathematical BS written about CAs, but they're quite interesting in their own terms). In particular, this is actually a non-deterministic CA. It's also a simulation. We can categorize both ways; this is just categorization, not a class hierarchy! (Except it is an ''ontological'' hierarchy; that's a rather more sophisticated thing though, and objects can be instances of many classes in ontological terms.) –[[User:Dkf|Donal Fellows]] 10:58, 5 April 2012 (UTC)
==task description==
Concerning the task's first rule (1):
* A burning cells turns into an empty cell.
... But how long does it burn? Everybody has assumed "one iteration" (or life).
<br>The same thing with rule (4), it appears that the tree fills the space (grows to maturity) in one iteration. -- [[User:Gerard Schildberger|Gerard Schildberger]] 20:39, 20 April 2012 (UTC)
:Don't worry about the physics of it. Just sub in lifeless letters. For rule 1 just think of it as saying "a B cell turns into an E cell" and for rule for think of it as "an E cell turns into a T cell with probability p". --[[User:Mwn3d|Mwn3d]] 15:18, 21 April 2012 (UTC)
:Usually, rules in cellular automata specify what happens at the next step, so it's safe to assume it's for just 1 iteration. --[[User:Silverweed|Silverweed]] ([[User talk:Silverweed|talk]]) 14:15, 10 October 2014 (UTC)

May the forest be with you. -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 13:43, 30 November 2019 (UTC)
