Children Per Family

[weimar_republic]

This cut and pasted from civfanatacs. maybe you guys can make sence of it. if so, contact me at weimar_republic@hotmail.com


here is what I have been able to find out on the children per
family:

city size-foodeaten-foodsurplus-children it makes
1-2-4-10.0
2-4-5-8.6
3-6-5-7.0
2-2-1-0.7
1-2-2-6.0
2-4-4-7.3
3-6-6-8.0
3-3-(-3)-(-1.0) size three with 3 food = -1.0 children
4-8-8-8.4
5-10-10-8.6
6-12-12-8.8
7-14-14-9.0
17-34-22-6.8
X=anything
X-2X-0-2.0
^^thats not it BTW

so, whats the formula here? anyone have any ideas?
it MUST have a +2 at the end...
so without the +2 it would be
2-4-5-6.6
2-2-1-(-1.3)
2-4-4-5.3
5-10-10-6.6
and others
...
hummm use a graphing calculator??

Marquis: in answer to your first question, this is the number for one city, which is averaged with the numbers for the rest of th cities in your civ to get the average cpf for your civ.

There is probably a formula where you take city size*food surplus*some other math junk=growth rate for that city.

Or you could just say:

The civ with the highest cpf is growing the fastest.......why does everything have to be broken down into a boring scientific formula?

because we're bored!!! That's why. We have nothing else to do until civ 3 comes out, so why not analyse every aspect of civ 2 so we understand most everything about civ 3 before it comes out.

2 + (4*food surplus)/(city size + 1)

I think you'll find.

Edit: That's rounded down to the next 0.1

I can confirm EOL's findings.

First question: Were these numbers for a one-city civ?

What IS clear about this jumble of numbers is that children per family (i'll call it cpf) = 2 is steady state, a.k.a. no population growth - 2 children replace the 2 parents. If this was what the designers used, we could suppose that cpf = 4 means the population doubles, cpf = 6 triples, and so on, in a certain period of time (turns? until the next pop. change?). These numbers are clearly rounded off to the nearest tenth.

The cases in which the surplus equals the food eaten graph a classic hyperbola (or is that a parabola? I can't remember any more...). A classic curve, in either case.

It must not necessarily have a +2 at the end, altho that is a likely possibility. The steady state 2 could be part of a numerator...

If rules.txt states that each citizen eats 2 bushels per turn, how can you explain the cases in which city size is not half of food eaten?

Testing should include an array of cities with eaten = surplus, to more accurately calculate the curve, size 1 cities with various surpluses, and some random larger cities/surpluses to sample. Any takers? Or have I volunteered by responding?

Um, well you could actually play the game Airdrik, wouldnt that cure your boredom??

[airdrik]

I am not one of these people who do the analysing, I just play. I haven't played civ 2 enough to get to the point where all I do is analyse. Though I think I will take your suggestion and play some more .

OK, nice work, but what about a civ with several cities? do you add the city sizes then?

My guess would probably you sum up each cities' size times it's family size and divide by the total of all cities' sizes and that is the number.

[EOL]

For more than one city

City size becomes the sum of all the city sizes = total no. of citizens
Food surplus becomes the net surplus across your empire.

Perhaps bizarrely, I think that food which goes towards supporting settlers and engineers also contributes to the food surplus for this calculation.
