AI Development Discussion and Feedback

Cernel

@redrum Ah, that would be cool to test. Sadly, for compatibility reasons, I cannot feasibly use the prerelease in lobby. Anyways, here it is the savegame (the game just finished on round 12 with West (that is me) winning by surrender):

DID AN ADMIN CHANGE ANY POSTER FORUM EMAIL NOTIFICATION SETTINGS?

I ask because I just opened up my email and see 5 emails from Triple A about this thread ... the email says I can adjust my email settings and gives the link and I saw 2 places where it will send emails so I changed it.

Was just weird I never got email notifications before (hate them) so something with this thread made me get 5 emails from these new replies but maybe the 2 places I just changed now I won't get emails

@Captain-Crunch Ya I also noticed I am receiving them again like in the past but I have not for awhile. I never changed any settings but perhaps @RoiEX did?

RoiEX

I didn't change the setting either, I had the same issue as well, but changing the setting was 10 seconds so I forgot about it

@redrum (or AI developer(s) -- Regarding assisting with AI for triplea.

First wanted to verify the last release is TripleA_1.9.0.0.13066_windows-64bit? And if I (us single-player/AI users of triplea) should be using, testing and commenting on the AI for 1.9.0.0.13066, or should we be using 'TripleA_1.10.14966_windows-64bit' (for instance) instead?
I received recent emails from axisandallies.org, which prompted me to d/l 1.9.0.0.13066 and play classic WWII 3rd edition, and notice what the AI was doing. So I don't want to waste anyone's time until I know which version I should comment on.

I think the AI in triplea has been excellent and a great endeavor. Thanks!

redrum

@Sculpt Responses:

1.9.0.0.13066 is the latest stable release. There have been some fixes and improvements since then which can be tested in the latest pre-release found here: https://github.com/triplea-game/triplea/releases. I recommend using the latest pre-release if you can so that you get all the latest changes but feedback on either release is still useful.
Great to hear. There are many great maps that you can download and play with TripleA. I'm glad to have AI feedback on any maps which you are playing.

Cernel

Playing "A Song of Ice and Fire" with all players assigned to HardAI the game crashed on round 16 at the start of the Combat Move phase of FreeCities.

You can find the link to download the map here:
http://tripleadev.1671093.n2.nabble.com/The-Game-of-Thrones-map-bug-tp7587435p7587606.html

You can play this map with TripleA 1.8.0.9, but only if unzipped and with a case insensitive system.

@Cernel I'm fairly certain that issue was fixed in 1.9. Once I update the map to 1.9 then we can try to reproduce it.

I was just playing Middle Earth on the latest AAA version. It seemed like the hard Evil AI wasn't quite aggressive enough. Other than that, they seemed to play very well, so thanks for all the hard work!

beelee

Idk if it's been 8 weeks or not or if this is even the right thread but for some reason I just ... well

Hard AI didn't seem to handle Strategic bombing very well. Was playing one of the star wars galactic war maps. First couple of times it sent several bombers in to bomb, but after I started to defend against it, it would send in 1 or 2 bombers when i had 4 fighters and AA in the area and just chewed them up. It was almost as if the AI didn't consider the fighters when it made it's calculations on if it would be worthwhile to do the bombing run.

Captain Crunch

@ff03k64 hmmmm was the AI winning comfortably at that point? Like they had Bombers to spare?

ff03k64

No, when it started getting bad it was pretty even. It continued for several turns as they were falling behind.

redrum

@ff03k64 Do you have a save game showing the poor SBR decisions?

ff03k64

@redrum starwarsforupload.tsvg

Let me know if that worked.

redrum

@ff03k64 Ah I see. In the current stable release (1.9.0.0.13066), the AI doesn't consider interceptors. Logic to handle this has already been added to the latest pre-release to avoid this exact problem you are seeing. You can try out the latest pre-release here or once we release the next stable release it should be fixed: https://github.com/triplea-game/triplea/releases

ff03k64

@redrum I think i will stick to the stable. I want to try to make a map myself, so i would rather not work with the pre-releases and their possible bugs at this point.

redrum

@ff03k64 Ok. You can also have multiple versions (say stable and pre-release) installed at the same time. You just need to make sure to pick a different install folder location when running the installer.

ff03k64

@redrum Oh yeah, I remember that from when I had like 1.3 and 1.4 at the same time. Is there a changelog for the pre-release?

redrum

@ff03k64 Not yet. We usually publish a consumable changelog when we release a stable. You can see the changelogs here but for the pre-releaes is just points to the PRs since the last stable which is quite a lot https://triplea-game.org/release_notes/
