Active city production ending when?

[Chazar]

When does production in active cities stop?

I seem to find active cities that stop with just two 2-turn units, and others that produce five 3-turners. Is this predictable somehow, or is the total number of units produced randomly determined?

it is predictable and is limited by either the city income (as it needs to support its defenders) as well as a max number of units. I dont remember the exact code right now though.

Arrgh, I guess that is the worst of all possible replies: it can be known, but it isnt known right now.

Well, it is good to know that it is predictable. So it makes at least sense to take measurements. Thanks.

I think we had a thread about this a year or so ago...we debated having a max limit on total STR in the city and some back and forth. i forgot the result of our convo and quite frankly, am too lazy to research.

Well, I did search the forums already, but I did not find anything relevant. I tried again now, and found this thread, which does not really tell us anything new.

I narrowed the upkeep sum to city income ratio to something between 0.60 and 0.74 already. However, I did not consider a limit on total strength yet to fit my obersvations.

if ($cityunits > 4)
{
continue;
}
if ($cityincome/2 < $cityupkeep)
{
continue;
}

So if there are more than 4 units in the city it wont build any. Or if the units in the city has an upkeep that is more than half the city income it wont build any new ones either.

Thank you!

I did not account for the imperative nature of the code (I believe in declarative languages), which is why I had already excluded 50% from my observation: A city with 15 income will thus build 3 units having an upkeep of 3, since 6 < 7.5, albeit the total upkeep in the end is 9 > 7.5, which corresponds to 60% city income being consumed by upkeep in the end in this particular example.
