@a-s The other AI's don't use UCT or any similar algorithm. They use heuristics based upon testing various possible moves for net TUV benefits and enemy counterattacks.

@thedog You may want to submit this as an actual issue with AI log. It maybe that it always focusing on the big opposing armies and view the neutral spaces as low priority.

@beelee I am in agreement. The current TripleA AI is pretty good, although it has some fixable glitches. I think the further improvements should come from the ability to create specific heuristics for the AI for specific nations and scenarios.

What isn't going to happen is the creation of neural net style AI that will play well. A&A is beyond the capability of current AI approaches to solve.

@dadude9211 The AI does not make any special effort to take or defend VC's. The AI does not normally try.to protect anything other than capitals or factories.

You could simply uncheck projection of power and check honorable surrender instead in the opening screen.

@TheDog Awsome, thats exactly what i was looking for.
Thanks.

@Trevan Currently, the AI simulates the current turn to the end to determine what it should purchase based on estimated moves/battles. It doesn't simulate future turns due to how quickly the search tree explodes and how long it takes to run. You would need an incredible amount of optimization and fairly accurate prediction of moves/battles to slim the search tree to achieve that.

@TheDog said in Lets help the AI purchase the unpurchaseable:

Would this AI project conflict with what Trevan is currently doing?

No. My AI is completely different from @redrum's. So changes to his ai wouldn't affect mine.

Here's an initial attempt to showing the values of the territories as a heatmap. This is World at War. It is from Russia's point of view. The bluer the territory is, the better it is. So most of the Russian territories are very red since the units shouldn't stay there.

@TheDog The value is used to prioritize which territories to try to defend (do I defend my capital or this factory or this random territory) not how much to defend them with. So this probably is not causing overstacking of capitals.

I would really want allowing map makers to create separate AI files for their games as well.

@TheDog Thank you for the maps

I think that TripleA needs some features to direct the AI. There should be is an IsAI condition available, as well as some new event types, such as PurchaseQuantity, PurchaseProportion, PurchaseUpTo TransferUnits. I will prepare a formal feature proposal.
