Where in the game files is this defined? I though it was common/countries/<country> but I frequently see AI taking other ideas than those from the historical set.
How AI choses which Idea Groups to take?

If you look into
"Europa Universalis IV\common\ideas\00_basic_ideas"
You will probably see that Russia/Muscovy doesn't pick Expansion (first), if they don't own at least one port ( aka as seen in the DDRJake stream).

Right but the rest of them (save for naval) has:
So it doesn't really explain anything.
Code:
ai_will_do = {
factor = 1
}Yes but I would rather know why for example Denmark goes for Quality and not Offensive. Is this random?
Go to 'Europa Universalis IV\common\countries' and look inside the country files, the order of ideas is found within the 'historical_idea_groups' brackets.
Going back to your initial question,
Yes many countries have defined national ideas.
Europa Universalis IV\common\countries\Denmark.txt
But they also can deviate from them, if they don't have a port.
Don't know if non-naval colonial idea groups can be replaced by AI nations.

So AI always takes ideas from the list in this order unless it doesn't have any ports, is this correct?
Yes.
If the nation does not have a defined 'historical_idea_groups' section in its country file (common with converted countries from CK2, for example), it'll pick ideas from top to bottom of the '00_basic_ideas' file.
I believe there's some AI logic that makes them choose ideas from their file in a different order if it tells them to take, say, three military ideas in a row.
AI will follow the list in country file, it will not however always follow it to the letter.
And that's what I'm interested in - what determines what AI is going to chose while not taking ideas from the list?
I wish they got rid of most prescripted choices of idea groups and instead relied on some clever scripting using modifiers, for the rare occasions of seeing Ireland or Morocco being early colonizers.
If it's not following the list (as in, it cannot take something from the list for whatever reason) it will take the first idea available in the 00_basic_ideas.txt file, like rageair said above.

I'm not 100% sure, but I think I've seen some countries take Exploration early in some games and later in others, sometimes not at all too.
Yes, I think that's the point. It should colonize given its position but never will since it cannot take Exploration.
The AI generally tries to spread out its ideas across all three categories and will rarely, if ever, take even two of the same kind back-to-back, and thus pretty much ignores the order in the file.
The order does, however, affect what ideas a nation will have in later starts, as when you move forward in the timeline like that, the ideas are taken in the order they're listed.

I do seem to remember Wiz saying a couple of months or so back that he was changing how the AI chose ideas for AoW. Might have misremembered though.
edit: Just checked, he said he wanted to do it when he had time, not in AoW
