![]() ![]() It lets you start with a simple naive AI that just plays randomly then extend it with a decision tree to improve the actions. ![]() This would be my recommended starting point. If you can find a data set of pinochle games this will help you immensely for any approach you take.Ī quick look around and my guess is that most free pinochle games with computer players are using an expert system. This is typically handled by using a large data set of historical games, preferably games from expert players. A Monte-Carlo Tree may be able to overcome this but the difficulty will be determining reasonable probability for each node. You may need to rework things when implementing the AI but it gives you a stable foundation to start with as bugs with the game rules will manifest as major issues in the AI which can be complex to debug.Īs you have realized because pinochle is not a perfect information game building a min/max tree is difficult, likely intractable difficult. My recommendation is to start with completing the implementation of the game rules to the point where you can play the full game with all human players. I'm not familiar with pinochle but it appears similar though more complex than hearts which is a game I've coded an AI for and let me warn you that building an AI for pinochle may be a long and complex journey. I checked out a lot of pinochle apps and websites and am impressed with their speed, which makes me think they likely aren’t using a fully fleshed out game tree and maybe are consulting some sort of precomposed probability tables instead. Would somebody mind pointing me in the right direction?įor those who don’t know, pinochle is a trick-taking game where you play with a teammate against another team two opponents and each player is randomly dealt 12 cards. I’ve done a lot of googling and reading about this issue, but everything still seems murky. Do I just make a game tree that contains every possibility of legal card that might be played after the player plays a card and then choose what play to make using minimax valuations? I’ve made simple AIs before for tic-tac-toe and such, but I’m not sure how to factor in the probability of this game. The user interface is coming along nicely, but I’ve never been great at the mathematical side of programming so I feel at a loss for where to start when programming the game’s AI. Hi everyone! Recently I started a fun side project of coding my favorite card game, which is pinochle. ![]()
