Sorry, I don't understand that. Especially the part about "rank barrior". Are you saying "nopt" does not equal OCN?
Yes, that's what I'm saying.
"OCN" is just that constant out of the editor.
Maybe just imagine an example. Let's assume you have two games which exactly look the same. Map, city layout, civ, city improvements etc are exactly the same in both games. Only that both games differ in difficulty, say warlord in one game and deity in the other.
Now pick the city called 'so-and-so' from both games (assume a specific rank etc) and crunch the numbers for Nopt...
See?
You use the same OCN for both calculations since the map size is the same for both games.
But. Nopt *is* different. It's lower in the deity city. The Nopt tells you the rank barrier (or "boundary" or whatever) for that single specific city you picked before bad rank corruption calculation applies. If the real rank of that city is higher than its Nopt, then it has the worse type of rank corruption.
Now while you're at it, you could of course imagine that both games also have the same difficulty. Then vary the other variables (one at a time) in Alex's formula and observe the different results for Nopt. OCN is still always constant here, though.
Of course, the interesting numbers for Nopt are those that are close to the rank.
Presumably nopt stands for something, or did someone join a bunch of random letters together? It might help me to understand what nopt is if I knew what it stood for acronym wise.
Well, take it easy. You could call it what you want as long as you define it. And it is very well defined in the first post.
I can't tell you why it's called "Nopt", nope.
The name is (TM) by PhD corr Alexman I think. It's just a kind of "modified OCN" for a specific city. It used to be called like that in the vanilla/PTW thread IIRC.
