Santase AI Player

About the Project

• Algorithms: Basically using sorted sets and sorted dictionaries with custom comparer. It is like taking cards in your hands and first of all - other them. Sorting provides fast access to the most low-point cards and in the same time to the most higher one.

• Ideas: Basically they are taken from here: http://psellos.com/schnapsen/strategy.html#closingthestock And added more improvements of choosing mechanics in some situations! (Like not switching J trump, counting points for closing conditions and a lot more.)

• Strategy: Basically the game consists of 2 stages and 2 different approaches based on witch player is on turn.

  • Opened Stack Stage:

  When are on turn, the process goes trough 4 stages:

  • trying to detect Close Conditions - and close the Stock if it is ok.
  • trying to Change Trump card
  • try to announce 20or40
  • play some low non-trump cars
  • and if nothing goes so far play any card ( from the ordered sets/dictionaries) When we have to answer to the other side is a little bit harder.
  • checking first, is opponent playing trump card - and try to run low on them
  • if it is non trump, then try to take with 10 or Ace to get big points.
  • if we cant we play Low Non-Trump but try to get the hand.
  • then we try to get it again with Low Trump card
  • and if all fail - try to avoid giving pints, by giving the lowest possible card

  • Closed Stack Stage:

  On Closed Stack the game changes a lot, but we have to think less. When we play first:

  • we must try to play winning-for-sure cards first.
  • if this fails - we check again for 20/40 announcements
  • and then play low - to give little points to the opponent. When we answer to the opponent moves
  • we check first if it is possible to win the take
  • if not, we play low.

• In the beginning we used standard Chain of responsibility pattern, but later we removed the anstracts(middle) class, becouse the ai.bgcoder.com - system, did not recognise witch public class with IPlayer in inheritance chanin is the main class. Now it is allmost the same method, but it it a little bit manual implemented in every class.
