AI blunders you would like to see fixed

[Beagá]

I will put 2 examples, feel free to put more. Absurd things I´ve saw (IMO).

1- Excessive troop use for sieges even when not needed. Mamelukes dropped 20k army total on Cyprus. That was alone with no allies. Isn´t it great to get disease outbreak on the only army you have? Of 10k infantry and 10k cavalry Yes it is (for AI Ottomans...).

2- AI DOWing for claims that are already occupied by a third party in another war. That one is a bit trickier, I admit. Sometimes it is a blunder, sometimes it is not. What i´ve saw was Burgundy fighting England for Caux (one of those porvinces in the north), occupied it, then France DOWed England too for Caux.

Basically being at war for several years for zero gain and no chance of one either. What could be done is making AI DOW only if the claim is not occupied and third party is too weak to probably beat the war target.

Been working a lot on attrition lately since that has been an obvious problem with the AI. Maybe it will be better in the near future.

Might revisit AI DOWs for the reason you mention, thank you for making me aware of this problem.

@Beagá Also, if you have any save games showcasing ridiculous AI attrition you would like me to inspect, feel free to upload. I need to verify my new code works.

 

[Beagá]

Sure



I´m afraid I didn´t get pic of 21k Mameluke stack on Cyprus however :/

On topic of CW, Lithuania and Moldavia are strangely passive regarding creation of claims on Crimea, Muscowy etc, something they did in the past... is there some option I must use in game to make them do it?

Also... dat Austria. Please do something about it too

Technically this isn't a blunder, as the AI gets no choice in the matter. But the AI really should have the ability to say no to aggressive succession wars.

 

[Zelius]

Sure

I don't see anything...? Burgundy in Ireland taking 1% attrition?

I believe ruler personality still determines how many claims they fabricate.

They do, however for some reason unless the odds are

Spoiler

really really really really really really really really

not in their favor then they wont challenge it.

The excessive attrition is a tricky one because if the AI started spliting up their forces too much it would be easy just to stackwipe small armies.

Best fix would be for them to put just as many men as necessary on the siege and then leave the rest in an adjacent occupied province.

If/than statement:
If attrition = greater than monthly manpower increase, than move troops.

With all the Ai bonuses this should do the trick.

Or you could program it a bit further by having them account for nearby enemy armies.

With your idea, country with 100 manpower recovery speed, sieging castle should move units during the winter out of the siege. Because that's 2% attrition from 6k -> 120 manpower loss; more than monthly manpower increase. And countries already being struck by negative manpower recovery speed like war exhaustion will have even more problems resieging their own lands. And don't even start with lands with +extra attrition, defensive +attrition, quantity +bigger garrisons, meaning more regiments needing to siege it; and or higher level forts, and cherry on top = capital forts.

Great idea

Thank you. Yeah already trying to deal with the other things you mentioned.

like this.

Might have a look if there's time, guess it's "not that tweaked" due to succession wars not being that common.

Recently implemented this, but it should be noted that AI also has to deal with cases of allies piling up along with them that are more difficult.

AI attrition logic is a few thousand lines of code, AI movement logic is tens of thousands. Try to explain in human terms instead because there is no simple code that works.

His idea was that if the atrition results in more than monthly manpower recovery move men from siege (divide stack, or reduce men on siege), which as I mentioned a little bit higher, is idea slightly less than ideal

Well I assumed they would program the AI to account for the use of mercs and other factors that are too numerous to list.
But anyway I'm not a programmer.

heh, this is why I'm not a programmer.
I make it sound easy with my "simple" if/then statement, but I do know its not.

But I'm also of the opinion that you might as well fix it right instead of slapping quick fixes ontop of quick fixes - this might not be the best effective use of time for a business but it does deliver a quality product.


If you factor in the time spent to fix the military access problem, then factor in the time to fix movement for attrition, and then fix the etc, etc, etc, it might be worth it to go through some of that code and fix right. Then you can also port that now effective code to EU5 or something.
But this method would surely not meet any deadline for DLC and would best be done by the guy who wrote the actual code - who may be on a different project altogether.

Keep in mind these literally just my educated guesses.

The AI has a tendency to send wayyy too many troops to the Americas to fight colonies in wars which involve European countries and wargoals.

In a recent Sweden run I got into a major war with HRE Bohemia, which was allied to a large Scotland.

Scotland send its main stack over to North America, allowing me to capture all of their European forts and signing a punishing peace.

They had virtually nothing to gain in the Americas given that the wargoal wasn't there and overseas occupations count very little, and everything to lose by leaving their homeland undefended (not only from me, also a rump England could have jumped on them).

It was a pity really because Scotland was doing well, having the upper hand in Britain and a fledgling colonial empire. This war marked the end to their ambitions though, as I demanded all of their colonies for next to no warscore.

In the same war Milan did a similar thing, albeit in smaller numbers due to lack of transports I suspect.

I suppose it wouldn't be too hard to prevent the AI from sending troops to theaters where no significant warscore can be gained.

As an aside, it's great to see the devs so engaged with the fanbase as in this thread.
