Have you EVUR been wondering "What AI should I use if I use World Airliners Set NewGRF"?
Propably not, and you never will, but anyways, here goes another of my extremely annoying topics calledAircaft AIs vs World Airliners Set
In this topic, I will describe you my process of testing aircraft-capable AIs with World Airliner Set, which adds many airplanes and liveries. Of course I am not expecting any AI to actualy change a livery, no one has ever made that (*wink wink*), but at least if anyone is interested in making it (*winking intensifies*) they can see which AI would be the best base. Basicaly only thing you would have to do would be making the AI randomly refit the aircraft, but hey...Okay, let's start withAI selection
Setting up AIs
- [+] Spoiler
- On the wiki I found a nice spreadsheet of AIs describing what transport types they can handle. Long story short; the list is outdated so here are my picks!
- [+] Spoiler
- I basicaly tried to use the most difficult setting available, as well disabling trains and boats, basicaly the AIs can only use planes and busses (for feeder services? can anyone actualy do that?). Also, all AIs SHOULD start at the same time after the game is launched.
Aaaaand I just found out that you can "only" have 14 AIs present, so I will have to choose 3 that have to go out :C
I chose WrightAI, because Rythorn Airline AI is it's fork (and it promises to keep it's mechanics), and NoCAB and it's Bleeding Edge version, because we have it's fork (NoNoCAB) present. I hope I did not trigger anyone.
Fun fact: at this point instead of "Preview" I cliked "Submit", but that has nothing to do with this topic at all
Sidenotes: I had some problems with Rythorn Airline AI's settings, because it is so customizable it hurts my kidneys, so I just left it at it's default setting, I think they are fair enough, also, SynTrans's only setting was not working for me, I could not change it, so I will proceed and tell it's author after posting this topic, aaand Terron limits it's airline length to 450 tiles
- [+] Spoiler
• Passangers: Symetric
• Mail: Symetric
• ARMORED vehicle class: Asymetric
• Other: Manual
Plane speed factor: 1/1
Max planes: 1000 (nothing for mah mighty AMD Athlon X4 880K muheheheh)
Plane crashes: Reduced
Vehicles/Airports never expire
AI construction speed: Very fast
And Disable trains and ships for AIs
- [+] Spoiler
- The one and only NewGRF present is WAS, specificaly WAS 2017-03-22 because bananas version is very outdated and I have never experienced any bug other that purely graphical, so it should work out just fine
Now let's explain those parameters:
• Enable standard planes: of course I will leave this disabled c:
• Base cost factor: I usualy ramp it up to 8x, but the when it's renewing time, it completely ruins my economy
• Base running cost factor: I set it so high because I want to compensate the 1/1 speed factor (and I want to keep that factor there)
• Ranges: I'm planning a very big map, so infinite ranges would be too much OP
The first try (UNSUCCESFUL)
- [+] Spoiler
As you can see the map will be very airline-firendly. Also the city generation settings are there to make cities more spread out over towns so some kind of Hub-to-hub airport lines will make more sense (if any AI can make them of course)
So, let's do a quick check of all settings so I don't have to restart the game, and let's
The second try
- [+] Spoiler
- Of course most AIs are beginning with slamming hub airport next to a large city, but none of them seems to be purchasing actual airplanes... Let's quickly jump through some AI's console logs! AdmiralAI failed horribly after it built it's airports and found out it does not have enough money to buy an airplane. However, I call BS on that because it has enough money to buy a smaller one, I guess it simply focuses on the largest one (Airbus A380) and refuses to do anything else... Hopefuly it will recover. AIAI also refuses to build airplanes, however it actualy has a reason; it says that if infrastructure mainteance is enabled, then airplanes are not profiable. Well, I could argue on that. Clueless ran into the same problem as Admiral, but it realized that it's better to give up airplanes and go full busses. Exactly what I did not want it to do. And of course DictatorAI has it's own variant of the problem. It is trying to figure out oil airline. And even though it has a nice selection of oil-compatible airplanes, it does not want to buy one... geez. After multiple minutes of analyzing the overall situation, EpicTrans decides to completely ignore the possibility of endless profitability with airplanes, and it just builds busses. NoNoCAB seems to be very surprised about how many towns there are, and judging from it's console log, it will stay surprised and idle for quite a time. PAXLink, like EpicTrans, is focusing on busses, but it is scanning cities for potential intercity lines. Oh, and remember what I was saying about my Athlon? Well, now that multiple AIs are starting up, I regret that I invested so much in my monitor instead of better CPU, my FPS is down to 0.5. I hope it's just because there are many AIs that are getting familiar with the map.
Oh Jesus Christ FINALY! The first airplane enters the scene! God bless you Rythorn Airlines! It actualy managed to make a succesful link between two airports, and it did the most logical thing and bought small cheap turboprop ATR42-300. Wait a minute... did I say SUCCESFUL? Of course it did NOT. The airports are too far away from each other and the small ATR can not fly there. I will just accept the situation instead of being sad and disappointed. And it keeps building more and more, now we are at 4 airplanes, all of them standing saying that they can not reach their destination :c
I'm afraid that all remaining AIs will follow the same pattern and this test will be over faster than I expected... Ohh, NoCAB just bought an airplane, it will propably be the same failure as Rythorn, let's take a look; of course. Well, to be fair, some of it's new livestock-carrying Boeing 737-300F's destinations are in it's range, but there are two that will make the line fail. But at least it gave me some hope, I can not lie. And we have SynTrans entering the battle with it's fleet of five Bombardier Dash 8-300s, and some of them can actualy reach their destination! Wow. Hopefuly SynTrans is programmed to sell it's airplanes that are not making money, then it could POTENTIONALY become a succesful airline. We still have 3 chances in form of non-present AIs waiting to be dragged in-game; TeshiNet, Trans, and WormAI. Let's see. Oh, and couple seconds after that SimpleAI decided it wants to enter the mighty airline world! And it is not cheap, it bought a single Boeing 757-200 and PLACED IT ON A WORKING LINE! Seems like SimpleAI is not so simple after all ( ͡° ͜ʖ ͡°)
Meanwhile, the rest of AIs joined the game, none of them buying any planes as their first mean of transport. I'm seriously thinking about restarting with 2Kx2K map with unlimited ranges of aircrafts.
After many months of me staring at all companies' aircraft windows open, suddenly, two Douglas DC-8-50 pop into existence uder Transe's window. And yes, ladies and gentleman, their destinations are in their range. Looks like Trans is actualy thinking about it's airport placement, even though it outputs nothing into it's console log. It is like a stealth nija airline (if that makes sense).
It has been October for about 20 minutes IRL, and I am afraid that my 500$ PC can not handle the AI overload, so we would not see any reasonable results without letting the game run over multiple IRL days. And even though I would love to do that, in Czech Republic we have very expensive electricity, so I will do this instead; I will save and end the current game, and I will place the save file here, if anyone is interested. After that, I am going to test idividual AIs on 2048x2048 map, and considering that no AI is capable of setting up airport feeder services, I will completely disable road vehicles.
- [+] Spoiler
- Mmmmmkayyy, after the big failure I've completely reset my mood, let's just start all over again, with new, smaller map, and without RVs.
AdmiralAI: Admiral went with the simple strategy of placing a hub airport next to the largest city possible. However, it is not purchasing airplanes. It ran into the same problem as in the first test, it is focusing on one, expensive plane that it can not afford. Well, so much for AdmiralAI.
AIAI: Just like AdmiralAI, it ran into the "no plane cycle" problem, where instead of looking for a cheaper plane, it just keeps trying to buy an unsuitable one. Well, actualy it knows that it can not buy it, so it just says "no suitable planes found". Goodbye, AIAI.
CluelessPlus: Welp, we have the same problem, "Can't afford air connections". Let's just move on, whadda u say huh?
DictatorAI: Same. It can not find suitable airplane for it's desired oil connection.
EpicTrans: This guy just completely ignored airplanes, even though other transport types are disabled, it is building bus stations. Also, I noticed that it actualy built one airport, but destroyed it afterwards. Let's wait if it will notice it's mistake...... Yup, it did, it tried to build an airplane, but judging from it's console saying Couldn't build the aircraft, it will propably not do anything else.
NoNoCAB: Hold on, NoNoCAB seems to be onto something, after long map analysis, it built 2 airports and 1 airplane (Douglas DC-9-50), it even tried to make a timetable for it, but just like the last time, the plane can not reach it's destination. Let's see if it will do something. Nope, it can't even do something, because it spent all of it's money and loan at the one unsuccesful airplane. Rest in peas sweet prinse
PAXLink: I see signs of inteligence there! Even though it built bus stops, it realized that it can not buy RVs so it moved on to airports. Now, I feel a little bit bad for it, because it is trying to build actual feeder lines to it's airports. It's sad seeing it trying, but too bad, rules are rules. But hey, even though it can not build busses, it bought it's own Boeing 737-300 and placed it onto a working line. Yay, this is the first AI in the second test that can make profit! Oh, and another 737-300! This is looking good. And suddenly it bought Fokker 70, indicating that it does not suffer from the "focusing on a single plane" disease. And another one!!! Hmm, now it seemingly randomly sold two Fokker 70s, strange. Oh no, one of it's new planes can not reach it's destination. What a deja-vu. Too bad, PAXLink, your "clever" behaviour was just a product of plain randomness.
Rythorn Airline AI: Too far to next destination
SimpleAI: All my hope is concentrated here. It jumped straight into the game and created a working airline with two Boeing 707-420s. And while it is buying more of them it kinda seems like it is flight range compatible. Noice. With every aircraft, it is receiving more money, and with more money, it is buying more aircraft. This is what I wanted to see. Oh, and it even bought a single Douglas DC-8-50, so it seems like it also does not focus on a single type. And it just bought Boeing 737-300. It has 10 airplanes operating now, and all of them can reach their destination. This is very good. Damn, the 737-300 just crashed and burned and died, let's see if it will replace it or if it's just going to forget about the route, but it did say "One of my vehicles just crashed" in the console. But it seems the crash did not do anything to it's already solid economy, because it quickly bought more 707s, now it has 15 ariplanes, all of them making money! The only thing that scares me is that every time it can buy a 707, it does so, without considering the possibility to save money for larger airplanes. And it is buying more and more, 17, 20, 26, 32, and it again went for 737, but also with a Fokker 70. I will just leave this AI alone, and will report you back when it buys some large airplane, if ever. Well, it just bought three Boeing 757-200s, which can hold 11 more passenegers than it's second larges Boeing 707-420. So, now I was away for like 2 minutes, and it managed to buy 150 AIRPLANES! And it is aiming for high capacity with it's largest member of fleet being McDonnel Douglas MD-11 with 293 passanger capacity. Okay, before it reaches 200, I've decided to set the aircraft limit to 200. Just temporarily, to see if it will go idle or if it will replace smaller planes with larger ones. And it bought 313 seated Airbus A340-500. And there goes the limit. Let's see how simple this AI realy is; nope. Sadly it is just stuck. I think only chance it has is if some of it's planes crashed, then it would get replaced with larger one. Let's move on from this AI for now, maybe I will revisit it later.
SynTrans: SynTrans started very modestly with a little fleet of Bombardier Dash 8-300s, and all of them can reach their destination. Let's see how it is going to continue. It seems to be a slower and calmer version of SimpleAI, it is buying more Dash 8-300s, but not as quickly as SimpleAI did with it's 707s. And it seems to be bulding a "single hub" network, where all of it's airplanes share the same hub airport, but have different secondary destination. Come on SynTrans, there are five thousand people waiting on your hub, y don't you buy a nice widebody jet to transport them all, you have enough money. Oh, what is that I see in your console? "Waiting for 669921"? It seems to set it's target aircraft, but at this speed it will take it a realy long time to afford it. The AI seems to be frozen, just waiting for it's money. Can't blame it though, at least it managed to make 6 working airlines. Now it has around 300,000 pounds, which is halfway to it's goal. I am realy excited to see what airplane does it want to buy! It has 520 thousand pounds now, but it seems that it does not want to pay off it's loan. Come on, I am super hyped for it's desired airliner! Oh no, I just noticed that one of it's 8-300s can not reach it's destination ._. You know what, I will forgive it, because remaining 5 airplanes are making a lot of money. And it has enough money now, aaaaaand HOLY BALLS it bought a frikin' Concorde! This guy seems to know what is he doing! Or not? Did he just ignore the low reliability of Concorde? We will see. It seems like it has chosen Concorde to be it's point of interest, because it is again waiting for enough money to buy a second one. But hey, with a single 2,342 km/h flight it made more money than the Bombardier fleet combined. I just want to see if it will go for widebody airliner such as Boeing 747 or Airbus A380. So let's wait... And it just doubled it's money goal, perhaps to buy 2 Concordes at once, or.... maybe something bigger? Heh.
Okay, at this point, I've decided to cheat it some money. Because, unlike SimpleAI, SynTrans realy seems to be going for it's goals instead of quick expansion. This would take A LOT of time, so here you go SynTrans, here you have 10 milion pounds, not that much with WAS, it can buy around 6 A380s, but it bought 6 Concordes, 9 now, and it sold the 8-300 that could not reach it's destination. Good. But yea, it spent all of it's money on Concordes, and is now waiting for more money so it can buy a Concorde. Nothing more to see here.
TerronAI: "Not enough funds to start action..."
TeshiNet: It seems that it is not compatible with airplane-only gameplay, because it has built it's truck stations anyways. Nope, it has built around 1000 road pieces, every time it finds out it can not buy a road vehicle, it removes it's stations and tries again, slowly draining it's budget to zero.
Trans: Trans went with the same strategy as SimpleAI, it placed two airports, but instead of 707s, it used two Douglas DC-8-50s. And it's long haul route is making hella lot of money. I predict very fast expansion! Exactly, it bought 2 Fokker 70s nad placed them on a shorter route with smaller airports. And two more. I have a feeling that this AI is just beginning to heat up. Aaaand NOPE. It just bought 2 Bombardier Dash 8-200Qs that can not reach their destination... And it keeps buing more of them. This AI does not know what "range" means... so sad.
WormAI: We built airports but don't have enough money yet to buy airplanes.
- [+] Spoiler
- If you want to compete againist an AI player with WAS NewGRF RIGHT NOW, I would suggest SimpleAI, but if you like slower, smoother game and you do not care about aesthetics and diversity, you should go for SynTrans.
But, if you are interested in developing a fork AI that would be fully compatible with WAS, then SimpleAI is your 100% choice. I did not see a single plane out of it's 200 that would not be able to reach it's destination, which seems to be a very big and fatal problem of all other AIs.
Talking about problems, overall there were only 2 of them; either the AI just focused on a single plane without considering buying a cheaper one, or it just did not care about the plane's range. That's what should be improved. Also, even though SimpleAI completely ruled this test, it had a very major problem. After it reached it's aircraft limit, it just stopped, even though it has more than enough money to upgrade it's fleet.
Thank you for your time and I hope to get a response
