Everything you wanted to know about corruption

Does the OCN factor determine which cities receive its benefits based on proximity to the palace / FP? Meaning, if the OCN is 16, do the closest 16 cities to the palace enjoy lower corruption due to OCN and due to the distance factor? Or is there some other manner of determining the OCN effects (or lack thereof). Put another way, once you've blown past the OCN, does the OCN factor largely go away and now corruption is down to pure distance / improvements / WLTKD?

The rank of each city for corruption due to number of cities is indeed determined by its distance to the capital/FP.

But once you blow past the OCN, the OCN factor does not go away. On the contrary, it increases at an even greater rate. At the limit, once you reach about 1.5 times the modified OCN (modified by corruption buildings, WLTK, commercial civ, etc) you will always get maximum corruption (95%), no matter what the distance from the capital.

why is my city 95% corrupt

Hi,

I have a city that is 11 sqares away from my capital. It has 22 corruption and 1 gold. I have a total of 15 cities and I'm using the standard map. I'm pretty sure I'm using the original version of Civ3 (no patches). I am playing emperor. I used your formula, and I found that the city should only have 65% corruption, but somhow it has pretty close to 95%!

here's my questions:

1) do rivers with roads over them allow you toget the 15% bonus for being connected to the capital?
2) is it possible that the optimal number of cities in the map i'm on is less than 15 (and I have gone over)?
3) could I be counting the distance incorrectly?

thanks,

Andrew

Good question. I have not tested this. But I would be willing to bet that roads crossing rivers does not affect connection status, just as it does not affect trade.

2) is it possible that the optimal number of cities in the map i'm on is less than 15 (and I have gone over)?

Not unless you changed it in the editor. On a standard map the OCN is 16.

3) could I be counting the distance incorrectly?

Actually, using the calculator for your settings in Despotism, I get 95%, so I'm not sure why you get only 65%.

Finally, although it doesn't seem to have any effect on your example, keep in mind that things have changed since the first release of the game that you have installed. Get the latest patch - it fixes lots of things and makes the game better.

Formula question

by this part of your formula:

Fc = Ncity / Nopt - 0.5, if Ncity > Nopt,

Do you mean this

        Ncity
Fc  =  -------  -  0.5
        Nopt

or this


Fc = Ncity / (Nopt - 0.5)

The above is the one (standard precedence of operators in algebra ). Fc has the same value for the two branches of the formula if Ncity = Nopt, so we get a continuous curve.

Thank you. Not everyone knows operator precedence order. On forulas like this, I like to make sure. I'll be looking into putting this into a speadsheet that I'm working on, so I needed to make sure.

Sorry, I didn't mean to sound like a smart-a$$. The spreadsheet sounds like a cool idea.

I'm playing diety on tiny map and doesn't have FP. Beside capital, assume that I have 8 other city. 4 are located at 5,1 from capital while the other 4 at 4,3. For that case, what are their ranks ? Is it :
a. 1,2,3,... based on distance and year they are founded
b. 1,2,2,2,2,6,6,6,6 or
c. 1,5,5,5,5,9,9,9,9
If the answer is c, then those 4 city is beyond Nopt of tiny deity
Great thread, btw

[alexman]

Good question. I would imagine it's b, but I haven't done any tests. What did you observe in your game?

[One_Brow]

My guess would be c as the formula seems more likely to be "number of cities of smaller or equal distance to the capitol" (c) than "number of cities of smaller distance to the capital, plus one" (b).

It could also be :

1,3,3,3,3,7,7,7,7

which would be "number of cities of smaller distance to the capital plus half the number of cities an equal distance to the capital", which would be a little more balanced.

[Ekanata]

I think it's (c). In my game last week, I cancel founding a city because on the next turn (almost) all of my other city getting more corrupt. I usually arrange my city at (4,2), (4,3), or (5,0) from capital and the one I cancel was the seventh (including capital). Btw, I haven't patch mine.

Edit : I forgot the location of the seventh city. On my last game, it doesn't occur anymore.

I've Implemented your formula to an Excel format and have published the results for the CivIIIDG in this Construction Shack - 700AD Corruption & Waste Statistics Thread.

from my spreadsheet, It appears to be (A), for the calculations. I do have a few discrepancies that are off from expected %'s, and that might be from time of city founding or some other variable. I'll investigate it as I get time.

Alex, If you want, I'll be happy to e-mail the spreadsheet to you.

Well, if anyone cares, I just discovered a missing detail in the formula:

Democracy and Republic add 10% to the OCN. This explains the slightly better corruption in Republic than in Monarchy, even though these two governments have the same distance corruption.

Merry Christmas!

is that present in both 1.21f & 1,29f?

[alexman]

Yes, it is. I just didn't detect it until now because it's such a small effect.
