How the AI selects Idea Groups

[Pinpinolo]

I've noticed a few trends in all my games, such as Poland and England ALWAYS pick Aristocracy.

While looking in the /common/countries file, i noticed there was a section in each country called "historical_idea_groups". Apparently used to define which Idea groups are given if you start at a later date.

I then checked France's historical idea groups and compared them to the one's France picked in my Sweden game, started in 1444, they were pretty much exactly the same.

Appreciate it if Wiz or someone could chirp in.

Don't they follow the scripted groups to the letter?

I agree that it picks the same ones as the historical file, but often in a different order. That order however seems to be the same every game. I'll perhaps muck about with them in my files to create some more optimal AI's. For instance, there's no reason for England to take Aristocracy or to a lesser extent Defensive. Especially taking Aristocracy as its first idea is liable to mess them up.

They pick from historical idea groups but try to balance between the different points, so if they already have a milgroup they won't pick another milgroup until they also have dip and adm.

If a historically naval nation somehow becomes landlocked will they still take the naval ideas?

Why does France often chose Exploration second when it is 3rd in the files? So frequently they snatch Brazil away from Portugal.
