// private int staticScore(Board board) { // int currPlayer = board.getColorNums(board.nextMove()); // int oppPlayer = board.getColorNums(board.nextMove().opposite()); // return currPlayer - oppPlayer; // } private int staticScore(Board board) { int currPlayer = board.getColorNums(board.nextMove()); int oppPlayer = board.getColorNums(board.nextMove().opposite()); // 检查对手的棋子数量是否为0 if (oppPlayer == 0) { // 如果对手的棋子数量为0，返回一个极大值 return Integer.MAX_VALUE; } // 如果对手的棋子数量不为0，返回当前棋手和对手的棋子数量的差值 return currPlayer - oppPlayer; }分析代码

这段代码是一个静态估值函数，用于评估当前棋盘状态的好坏程度。它计算当前棋手和对手在棋盘上拥有的棋子数量之差，如果对手没有棋子了，返回一个极大值。这种情况下，当前棋手是胜利者，因此返回一个极大值可以确保 AI 会尽可能地选择这个状态。如果对手还有棋子，返回当前棋手和对手的棋子数量的差值，这个差值越大，表示当前棋手在劣势，越小则表示当前棋手在优势。
