By algorithm I mean a special formula which is the base of daily calculating work done by the computer.It seems you still have a slightly wrong picture of how this SIM works. Itīs a one-man show (or a few more in background for help), it is not a full team of specialists running it manually. Nearly everything works on a routine, and only in rare exceptions things are tweaked manually.
But this is exactly what you want: special tweakings for every country,special country combos, for every major airport and so on.
The examples you mentioned were general problems of calculating routines and they were solved by tweaking the general formulas valid for the whole game.And fuel prices are the product of an algorithm which also includes random aspects, so not even Sami knows, when itīs going to spike.Please consider these questions before just stating everything is "doable":
Who is going to work out the thousands of exceptions that exist to reglement aviation business, for past,present and future?
Who is going to tweak the database manually for this mass of information, not thinking of verifying if informations are correct?
Who is going to inform the community of every special regulation that might limit the opening of routes?
