AdmiralAI v25

[Dimension]

AI's loaded trains often go to the way with low reliability.

If it may be possible, can you teach AI to build a depot on the other railway? So loaded train go first to the depot and then go to the next station with full reliability.

Well i tried to load the save file to play and guess what, it crashed on me for some reason. Can u enlighten me pls Yexo? I don't think you get what i mean. I meant starting 7 of them and only 1 or 2 manage to start off, the rest just had their values reduced to 1 pound

Loading a savegame indeed crashes NoAI now (will hopefully be fixed in next nightly), but can you still upload the savegame?

What I tried to explain in my last post: If you start AdmiralAI 7 times, they will all try to build the same route, but most of them will fail, so only lose money. You better start only 1 or 2 at a time (that is, untill I fix that issue in AdmiralAI properly).

Sure, it already does build a depot on the other track, but that depot will be near to the unload station.
About your game: Do you have breakdowns disabled and maybe also the option "Vehicle need not to service if breakdowns is off"? If not, can you post a savegame too?

Hmm ok thanks yexo

[Yexo]

Hmm ok thanks yexo

That is not a NoAI savegame. Did you download a NoAI nightly and play with that? The AI in your savegame is dumb because it's the 0.6.x and trunk AI.

[XxInNOutxX]

Yes im sure i dlled noai openttd
EDIT: OOPS uploaded the wrong one im super sorry

[Yexo]

Yes im sure i dlled noai openttd

Then you either uploaded the wrong save or you didn't start the NoAI binary. (This save is loadable in 0.6.3, NoAI saves are not)

[XxInNOutxX]

I now uploaded the correct one

[Yexo]

I now uploaded the correct one

Don't start the AI that many times (max 3) and give them some more years to build a route.

Ok thanks btw when do u intend to implement the ability to load AdmiralAI saved games? Just a casual qn

Of course. I'll fix that in v15.

[XxInNOutxX]

Will be eagerly waiting for v15! Good luck on that development of v15

Yes, that network was completely build by a branch of AdmiralAI, but not the version you can download here.

I took a look at your delaunay triangulation code, but I found it too slow especially on bigger maps with a lot of towns (try 2048^2 with high towns). I currently use the follow strategy:
1. Only use the top 1/3 biggest towns. This value maybe needs adjusting dependend on the total amount of towns / map size, but for now it's a good estimate.
2. For every town in this list, get the 3 nearest neighbours in all directions (N, E, S, W), and evaluate the connection between them. For the evaluation, get all neighbouring towns, and disallow the connection if it is the long side of a triangle with a big angle, allow it otherwise.

With this algorithm I can plan a network on 2048^2 with high towns in about 5 game days. Creating all signals so I can view the networks takes way longer of course. FYI, the screenshots shown above where created less than 5 years after the start of the game and all planned connections are build.

Besides this, I created several functions to cluster nearby towns, but those are currently not in use. I might run this clustering first and connect all clusters instead of only big cities.

@zutty: I'll clean up my network building code and send it to you.

Seeing your post in the cargodest topic, have you already merged the branch mentioned above (i.e. is your current build 'cargodest-proof')? Would be fun to play against AI with cargodest !

I have not yet merge my cargodest branch. However, the current version will work with cargodest, it it only builds point-to-point routes and those aren't affected by cargodest.

Please, Yexo, do anything with railroad depots.

[Dimension]

hm... It has happen because trains can not go forward. Some error with signals or else.

I'll have a look at it before I release the next version.

If you set "show pbs reservations" to on, you can see that the tile in front of the first train is reserved. I have no idea by which train, but this is a bug with pbs, not with my AI (all signals are correct, this situation should never happen).

AdmiralAI doesn't seem to take into account that with PBI's steel mills, only transporting coal to it isn't really a good idea. Other than that, it seems to be quite smart!

EDIT: also, it's having problems circumventing this sawmill.

Savegame attached, I haven't found out how to show errors/debug info/whatever.

The AI has no way of knowing that steelmill also requires iron ore. The only way it can find out is by trying and I've not implemented that yet.

EDIT: also, it's having problems circumventing this sawmill.

My best guess is that the sawmill wasn't there when the pathfinding started.

You can open the ai debug panel under the question mark in the main menubar.

Thanks for your report

the unnamed guy in the pic is the admiral AI but i haven't got any ''new transport company started building in some town'' message so it hasn't really started yet. in another game with the admiral AI it started immediatly with a cargo route but it builded only the two station and no track. I am using DB set Xl, AV8, eGRVTS and some other smaller grf's with version r14552 noai. no vehicles are disabled for the computer.

Can you post a screenshot of the AI Debug Panel (found under the question mark in the main toolbar) when this happens again?
