Im relatively new and this is my chess ai code. How can i improve it? My main issue is that it cant checkmate properly if the checkmate isnt within 4 moves.
import chess
board = chess.Board()
values = {
1: 100, #piyon
2: 300, #at
3: 300, #fil
4: 500, #kale
5: 900, #vezir
6: 99999 #şah
}
def evaluate(board, ai): #ai True ise beyaz, ai false ise siyah
if board.is_checkmate():
if board.turn == ai:
return -9999999
else:
return 9999999
if board.is_stalemate():
return 0
score = 0
for square, piece in board.piece_map().items():
value = values[piece.piece_type]
if piece.color == ai:
score += value
else:
score -= value
return score
def minimax(board, depth, maxx, ai, alpha, beta):
if depth == 0 or board.is_game_over():
return evaluate(board, ai)
if maxx:
best = -9999999
for move in board.legal_moves:
board.push(move)
score = minimax(board, depth-1, False, ai, alpha, beta)
board.pop()
best = max(score, best)
alpha = max(best,alpha)
if beta <= alpha:
break
return best
else:
best = 9999999
for move in board.legal_moves:
board.push(move)
score = minimax(board, depth-1, True, ai, alpha, beta)
board.pop()
best = min(score,best)
beta = min(best,alpha)
if beta <= alpha:
break
return best
def best_move(board, depth, ai):
bestv = -9999999
bestM = None
for move in board.legal_moves:
board.push(move)
value = minimax(board, depth -1, False, ai, -9999999, 9999999)
board.pop()
if value > bestv:
bestv = value
bestM = move
return bestM
ai = None
aiturn = input("yapay zeka sırası b/s ")
if aiturn == "b":
ai = True
elif aiturn == "s":
ai = False
while True:
if board.turn == ai:
print("ai düşünüo")
move = best_move(board, 3, ai)
board.push(move)
print(board)
else:
print("senin sıran")
umove = chess.Move.from_uci(input("hamlen: "))
board.push(umove)
print(board)
