示例1: GlobalExchangeEvaluation
Score GlobalExchangeEvaluation(Board &board, std::vector<Move> &pv, Score currentEval, Score lowerBound, Score upperBound)
{
assert(pv.empty());
// try standpat
if (currentEval >= upperBound)
{
return currentEval;
}
else if (currentEval > lowerBound)
{
lowerBound = currentEval;
}
MoveList captures;
board.GenerateAllLegalMoves<Board::VIOLENT>(captures);
std::vector<Move> subPv;
for (size_t i = 0; i < captures.GetSize(); ++i)
{
Score see = StaticExchangeEvaluation(board, captures[i]);
// we only want to search positive SEEs (not even neutral ones), and only if it can possibly improve lowerBound
if ((see < 0) || ((currentEval + see) <= lowerBound))
{
continue;
