I've successfully solved the Prisoners' Dilemma tournament problem using Answer 
Set Programming with clingo.                                                    

Key Results:                                                                    

 • Best Strategy: DEFECT with expected score of 48                              
 • TFT: Expected score of 35                                                    
 • COOP: Expected score of 30                                                   

How the ASP Solution Works:                                                     

 1 Strategy Modeling: Defined predicates for each strategy's behavior (COOP     
   always cooperates, DEFECT always defects, TFT copies opponent's previous     
   move)                                                                        
 2 Game Simulation: Modeled the 2-round game dynamics with proper state tracking
   between rounds using game_state/5 predicates                                 
 3 Score Calculation: Used ASP aggregates to:                                   
    • Sum round scores into game totals                                         
    • Weight game totals by opponent counts (5 type_A, 3 type_B, 2 type_C)      
    • Calculate expected total scores for each strategy                         
 4 Optimization: Used #max aggregate to identify the strategy with the highest  
   expected score                                                               

The solution correctly identifies DEFECT as optimal because it exploits the     
opponent pool composition (5 always-defect opponents where mutual defection is  
best, and 5 cooperative opponents where defection yields maximum payoff).
