上一章已经说明了被动出牌算法基本的出牌思路,且以单牌为例给出了具体的代码。
对牌、三不带牌型实现方法与单牌基本类似。改动的地方主要是枚举牌类型,出牌时value_nPutCardList的处理,回溯时value_aHandCardList和nHandCardCount的变化等几个方面。下面给出完整代码:
/对牌类型 else if (clsGameSituation.uctNowCardGroup.cgType == cgDOUBLE) { //剪枝:如果能出去最后一手牌直接出 CardGroupData SurCardGroupData = ins_SurCardsType(clsHandCardData.value_aHandCardList); if (SurCardGroupData.cgType != cgERROR) { if (SurCardGroupData.cgType == cgDOUBLE&&SurCardGroupData.nMaxCard>clsGameSituation.uctNowCardGroup.nMaxCard) { Put_All_SurCards(clsGameSituation, clsHandCardData, SurCardGroupData); return; } else if (SurCardGroupData.cgType == cgBOMB_CARD || SurCardGroupData.cgType == cgKING_CARD) { Put_All_SurCards(clsGameSituation, clsHandCardData, SurCardGroupData); return; } } //-------------------------------------------对牌------------------------------------------- //暂存最佳的价值 HandCardValue BestHandCardValue = get_HandCardValue(clsHandCardData); //我们认为不出牌的话会让对手一个轮次,即加一轮(权值减少7)便于后续的对比参考。 BestHandCardValue.NeedRound += 1; //暂存最佳的牌号 int BestMaxCard = 0; //是否出牌的标志 bool PutCards = false; for (int i = clsGameSituation.uctNowCardGroup.nMaxCard + 1; i < 18; i++) { if (clsHandCardData.value_aHandCardList[i] > 1) { //尝试打出一对牌,估算剩余手牌价值 clsHandCardData.value_aHandCardList[i]-=2; clsHandCardData.nHandCardCount-=2; HandCardValue tmpHandCardValue = get_HandCardValue(clsHandCardData); clsHandCardData.value_aHandCardList[i]+=2; clsHandCardData.nHandCardCount+=2; //选取总权值-轮次*7值最高的策略 因为我们认为剩余的手牌需要n次控手的机会才能出完,若轮次牌型很大(如炸弹) 则其-7的价值也会为正 if ((BestHandCardValue.SumValue - (BestHandCardValue.NeedRound * 7)) <= (tmpHandCardValue.SumValue - (tmpHandCardValue.NeedRound * 7))) { BestHandCardValue = tmpHandCardValue; BestMaxCard = i; PutCards = true; } } } if (PutCards) { clsHandCardData.value_nPutCardList.push_back(BestMaxCard); clsHandCardData.value_nPutCardList.push_back(BestMaxCard); clsHandCardData.uctPutCardType = clsGameSituation.uctNowCardGroup = get_GroupData(cgDOUBLE, BestMaxCard, 2); return; } //-------------------------------------------炸弹------------------------------------------- for (int i = 3; i < 16; i++) { if (clsHandCardData.value_aHandCardList[i] ==4) { //尝试打出炸弹,估算剩余手牌价值,因为炸弹可以参与顺子,不能因为影响顺子而任意出炸 clsHandCardData.value_aHandCardList[i] -= 4;

return; } //三牌类型 else if (clsGameSituation.uctNowCardGroup.cgType == cgTHREE) { //剪枝:如果能出去最后一手牌直接出 CardGroupData SurCardGroupData = ins_SurCardsType(clsHandCardData.value_aHandCardList); if (SurCardGroupData.cgType != cgERROR) { if (SurCardGroupData.cgType == cgTHREE&&SurCardGroupData.nMaxCard>clsGameSituation.uctNowCardGroup.nMaxCard) { Put_All_SurCards(clsGameSituation, clsHandCardData, SurCardGroupData);

return; }
接下来我们说一下顺子的处理方法。以单顺为例:
首先在第一阶段判断是否同类型牌里要额外增加一个条件,即顺子长度要一致
if (SurCardGroupData.cgType == cgSINGLE_LINE&&SurCardGroupData.nMaxCard>clsGameSituation.uctNowCardGroup.nMaxCard &&SurCardGroupData.nCount== clsGameSituation.uctNowCardGroup.nCount) { Put_All_SurCards(clsGameSituation, clsHandCardData, SurCardGroupData); return; }
然后除了设置BestHandCardValue等变量外,我们需要额外设置几个关于顺子的标志
//验证顺子的标志 int prov = 0; //顺子起点 int start_i = 0; //顺子终点 int end_i = 0; //顺子长度 int length = clsGameSituation.uctNowCardGroup.nCount;
遍历顺子的方法有点类似于最大子段和问题,大家可以参考下我以前的博客http://blog.csdn.net/sm9sun/article/details/53240992
解决思路就是如果出现某张牌个数为0,那么必然不存在经过他的顺子,此时就把计数器置零,如果计数器长度大于等于length,即可以组成顺子,我们以当前下标i为最高标志构造出(i-length+1)~i的顺子。
举个例子:对方牌型为34567,我从4遍历至8,若满足,此时end_i=8,即45678,继续走到9,若还满足,end_i=9。即56789,若没有10,则prov归零,下一次循环若11存在,则prov=1。
for (int i = clsGameSituation.uctNowCardGroup.nMaxCard - length + 2; i < 15; i++) { if (clsHandCardData.value_aHandCardList[i] > 0) { prov++; } else { prov = 0; } if (prov >= length) { end_i = i; start_i = i - length + 1; for (int j = start_i; j <= end_i; j++) { clsHandCardData.value_aHandCardList[j] --; } clsHandCardData.nHandCardCount -= clsGameSituation.uctNowCardGroup.nCount; HandCardValue tmpHandCardValue = get_HandCardValue(clsHandCardData); for (int j = start_i; j <= end_i; j++) { clsHandCardData.value_aHandCardList[j] ++; } clsHandCardData.nHandCardCount += clsGameSituation.uctNowCardGroup.nCount; //选取总权值-轮次*7值最高的策略 因为我们认为剩余的手牌需要n次控手的机会才能出完,若轮次牌型很大(如炸弹) 则其-7的价值也会为正 if ((BestHandCardValue.SumValue - (BestHandCardValue.NeedRound * 7)) <= (tmpHandCardValue.SumValue - (tmpHandCardValue.NeedRound * 7))) { BestHandCardValue = tmpHandCardValue; BestMaxCard = end_i; PutCards = true; } } }
最后打出顺子的话在start_i和 end_i区间内依次减一即可。
if (PutCards) { for (int j = start_i; j <= end_i; j++) { clsHandCardData.value_nPutCardList.push_back(j); } clsHandCardData.uctPutCardType = clsGameSituation.uctNowCardGroup = get_GroupData(cgSINGLE_LINE, BestMaxCard, clsGameSituation.uctNowCardGroup.nCount); return; }
以上就是单顺的处理方法,下一章我们继续填充其他牌型的出牌方法。
