SUGGESTION: AI troop building algorithm

[proteus]

That is true...you were right, this was my example. pI am never using LI for example, but maybe it is useful as well, just not for the AI.]

Hmm, it's a bit difficult to follow without graphical representation.

ok, here it is:

I'll continue the test game this weekend.
Meanwhile here are some improvements to the (pseudo-)code:

code:

---

[if there are multiple troops that fit a condition, mix equally,

      starting with the most ressource-costly first]

[bless effect=true IF 3 pathes @4 OR 1@6/1@4 OR 1@9 or better]



0)  IF ERMOR(Ash, Soul)OR PANGAEA(CarrWoods) GOTO 2)

    CALL BUILDCASTLE     



    IF (availablemoney) STILL >400 

        BUILD lab where's a special commander(mage) to build

    IF (availablemoney) STILL >(templecost*2)

        BUILD temple at

         - prov. that offers special holy commanders (mages, priest=3, dunno)

         - prov. that have a castle

    IF (numberofprovinces)>(numberofcastles)*4

     AND   ((turnnumber)-(numberofcastles)*10)*10%=true SAVEMONEYTURN=true; SKIP 1-3)





1)  Build troops at home province

     - IF prophet=false BUILD priest-3 or better

     - most expensive mage commander (80%:max. 1/2 of available money/ 20%: max.3/4)

     - assassin/spy/bard etc. IF ((turnnumber)-5)*10%=true

     - priest w/o magic IF (turnnumber)>(numberofpriests)*3

     - most heavily armored commander IF (turnnumber)>5 AND 'unusedleadership'<10

     - scout (50 - (turnnumber)*2)%



     - holy troop IF (bless effect)=true AND 3 pieces possible

     - heavy troopsress)>14 with (strat move)>1, best move first IF 2 pieces possible

     - heavy troopsress)>14 IF 3 pieces

     - medium troops: (ress)>10 IF 3 pieces

     - archers: IF Long-/Compound Bow





2) build troops at castles [highest ress value goes first]

     - most expensive mage commander (max. 1/2 of available money)

     - assassin/spy/bard etc. IF ((turnnumber)-5)*10%=true

     - priest w/o magic IF (turnnumber)>(numberofpriests)*3

     - most heavily armored commander IF (turnnumber)>5 AND 'unusedleadership'<10

     - scout (50%)



     - holy troop IF (bless effect)=true AND 3 pieces possible

     - heavy troopsress)>14 with (strat move)>1, best move first IF 2 pieces possible

     - heavy troopsress)>14 IF 3 pieces

     - medium troops: (ress)>10 IF 3 pieces

     - archers: IF Long-/Compound Bow



     

3)  Build special troops [in non-fortress prov]

     - special commanders IF mage

       OR

       IF special troops ARE undead, amphibic, flyers, stealthy

     - build as many special troops as ressources, (availablemoney)/2, (commandvalue) allows



 

4)  Build patrols at province w/o castle and less than 20 troops on patrol

     IF 

         borders enemy prov.

      OR has lab, but no castle

      OR has only 2 land neighbours

      OR has 3 neighbours, but only 1 owned

     

     THAN BUILD

     - most mobile commander IF (numberoftroops)>(commandvalue)

     - highest movement troop[for patrol]





5)  Build troops at all castled prov. [high ress value first]

     - light troops: (ress)>7 IF 3 pieces

     - fill with light archers/slingers



6)  Build troops in prov

     IF 

         borders enemy prov.

      OR has lab, but no castle

      OR has only 2 land neighbours

      OR has 3 neighbours, but only 1 owned

    - heaviest inf (50%)

    - archers (no matter what)

[Arralen]

I must admit - it's not only Gandalf who can't play as an AI would, strictly follwing the 'build script' .. I can't do it either. After 6..10 turns I simply screw up .. either I overlook something I'm supposed to do, or I start doing things I shouldn't

So if there's anyone out there interested in an AI that does not only build Light Infantry, please test this building script. If it works well, the devs may put something similar into the game, maybe.

[ioticus]

Where do I get this mod, and how do I install it?

[Kristoffer O]

It's not a mod. It's a suggested AI algorithm. In other words its an attempt at making a strategic manual for the AI. Print it out and play a game with those rules and never take any initiative of your own and you are playing the game acording to the Arralen AI Algorithm. If tested and proven good it might inspire JK to alter the current algorithm. If you come across any problems notify Arralen. He seems to be up for input .

[Gandalf Parker]

Its a set of AI rules. People keep saying "broke" but they rarely come up with specific suggestions such as this thread did. There is also another one like it on AI castle building somewhere.

The reason it needs testing is that its not hard to come up with specifics on how Ulm would play better or how Ermor would play better. But there is only (at this time) one AI program. So if you were to write a generic AI using words like infantry, cavalry, archer, mage, priest... then will it make things worse when played by Pangaea, or Caelum, or Atlantis.

[The_Tauren13]

I think I'll attempt to test this, so wish me luck; I'm not sure how hard it's going to be.
