谢邀&br&&br&喜欢啊！我五年前就学会斗地主。我平时不打牌，但觉得这个游戏特别好玩，也打算向美国人宣传中国最神奇的游戏。对了，我们在昆明的老外习惯把斗地主翻译为“F**k the landlord”。

一姑娘跟我说的事儿。&br&&br&他们现实里打带钱的，她是地主，没王没二，甚至连A都没，就要了地主。&br&&br&然后她那其中一个朋友就笑着说，你这牌也敢要地主？我俩王四个二呢。&br&&br&另一个也附和着说，我这儿也有炸哦。&br&&br&结果这姑娘也硬气起来了，问，我要是赢了怎么办？&br&&br&朋友笑着说，吹吧。&br&&br&姑娘就又说，我要是赢了你们一人给我一百，我输了给你们一人一百怎么样？&br&&br&朋友答应了，大家就都把钱掏出来放在了一起。&br&&br&该她出牌了：&br&&br&991010jjqq&br&&br&她二十张牌一次全打出去了。&br&&br&朋友还在诧异的时候，她已经把桌子上的四百块收进了口袋。

主要是多打。多思考，。然后需要用心去玩，要认真记忆牌。特别是J以上的大牌和自己手里没有的牌有一定要记住&br&一：记牌有一点很重要，就是必须记住外面出过的大牌(至少K以上，10以上更好，这样才能断定你手上的牌有没有最大)及你上家出过的小牌(这样便于帮助上家逃走，或者能用较小的牌顶住地主上家的牌以便自己有机会逃走)，可能的话最好记一下牌有没有出全，以防炸弹&br&二:叫牌。在叫牌时最好不要冲动，手上应当至少有两手绝对控制牌才行，比如一个大王加一对2，这样出单或打对都可以控制，有不少朋友喜欢冲动，手上有一把炸弹第一个就叫到地主了，这样一般情况下都做不成地主的，而且根据牌形同型的原理，别人手上有炸弹的概率很大的，那样的话就会输较多的分数。&br&三:出牌斗地主要长分快就要多做地主，做地主时应以安全为上，尤其手上有双王时该拆就拆，这样就有两手单牌的控制，而不要寄希望别人给你过牌结果使你舒舒服服的把双王炸出去，同样在不能确定外面有没有比你手上炸弹更大的炸弹时，可以出四带二，只要赢6分就行，因为冒险的话，赢了得分翻倍12分，但输了至少减少6分，而且万一人家真有大的炸弹炸了，那就要输12分甚至24分，所以从得失分考虑，做地主时安全为上。&br&四:配合但玩斗地主的乐趣就是斗地主，不让地主轻轻松松的做成，体现斗地主的水平也就是如何两人配合不让地主得逞。地主的上家首先要顶牌，除非是手上有绝对控制牌，甚至比地主的牌还好，一般说来，只要不让地主有出牌的机会，虽然自己不能逃走，但能给另一家创造机会走掉。&br&地主的上家在自己获得出牌权而又无法断定地主的牌型时，先应该出自己有把握控制的牌张，否则应当出较多的牌张，例如顺子或三带一，实在不行也应该出对子，在最没有把握时才出单张(但应该出较大的牌以顶住地主，必要时可把较大的对子拆成两个单，这样也是放信号给另一家表示自己无控制牌)，在顶单张时基本上应当比10大，有可能的话最好先顶住3张底牌(A，2，王除外)，这样的话便于最后根据地主手上的底牌来判断牌形。&br&地主的上家在自己没有控制牌时不要去跟自己的上家放出来的牌(单张顶牌除外)，例如上家出了5张的小顺，可能他手上还有6张的较大顺，如果你顺手跟了把5张顺，而地主又正好没有顺时，你就相当于在帮地主斗你上家；有时候上家出了个小对子，你手上正好只有一对小对子可跟也不要跟，因为万一上家的牌不好也想放牌给你，见你跟对子了他就要误会他放对牌了，结果等地主也跟对子后上家就会放手，这样就白白的送给地主一次出牌机会，而且有时候打到最后要渡牌给上家就是靠放小对子，因为在你的顶牌之下地主很容易出现最后只剩双王加两单或者光剩一个较大的单张等机会，如果你无法渡牌给你上家，那就把胜利拱手相让给地主。&br&当然地主的上家在自己的牌不算很好但比较顺畅时可以先脱手只剩单张等你的上家来放你，这时候在有机会出单张时不必顶了，而必须先出最小的单牌。地主的下家则要能跟就跟，有机会跑就跑，最好只剩一张或一对，这样就给地主出了难题，在走牌时也有一定的技巧，例如手上有AAKKQ6，对子已经是最大的了，应该先出K对，地主不要的话你再出6，这时候你的下家应当可以推断出你还有比K对大的对子，如果没有的话，你手上有三张单牌就死定了，那也只能死马当作活马医，所以他有机会出牌的话就应该出对子，除非他没对或者能自己走掉。&br&如果自己手上有炸弹但其他牌不是很好不容易走掉时，要注意不要先把最小的牌打掉，往往你的下家有机会跑掉，你只要确认你的炸弹最大了就可以炸他一把，不管是地主还是下家，然后把下家放走就行，如果你把最小的牌都打光了，就有可能炸了后放不走下家，结果弄巧成拙，反倒是让地主赢得了双倍的分数。斗地主游戏主要就是要记的准,配合的好,一般的情况下应该没什么问题的。&br&哈哈，这就是我在土猪游戏平台玩斗地主之前找的一篇攻略，还不错哦！你可以看看，对你应该是有帮助的

打牌不一定要会打，但摔牌一定要响！而且炸弹这种东西最后出就没有震撼力！ 必须开始就出，他出对三你就炸，炸的他意识模糊，炸的他甚至开始怀疑人生！

斗地主一局中炸弹出现的概率(≈0.5445)确实挺大，下面是我的推导思路(动态规划)：&br&&br&“至少一人有炸弹”与“每个人都没炸弹”互为对立命题，方便起见我们先求“每个人都没炸弹”的概率。&br&&br&假设当三个玩家(A、B、C)的座次选定，一副牌随机打乱发完时，A得到1-17号、B得到18-34号、C(地主)得到35-54号。现在不妨把这个发牌方式转化为另一种等效的方式：先发4张1，从A、B、C的54个牌位中随机挑选4个位置，再发4张2，从剩下的50个排位中随机挑选4个位置……因此整个发牌过程就划分成了14个阶段(13*4普通牌+1*2Joker)。&br&&br&现在我们需要每次发的4张普通牌(或者2张Joker)不能落到同一段(1-17、18-34、35-54)，因为同一段的牌位属于同一个人，这样就构成炸弹了。&br&&br&定义&img src=&///equation?tex=d_%7Bijk%7D%5E%7B%28m%29%7D& alt=&d_{ijk}^{(m)}& eeimg=&1&&表示在第&img src=&///equation?tex=m& alt=&m& eeimg=&1&&阶段、A获得&img src=&///equation?tex=i& alt=&i& eeimg=&1&&张牌、B获得&img src=&///equation?tex=j& alt=&j& eeimg=&1&&张牌、C获得&img src=&///equation?tex=k& alt=&k& eeimg=&1&&张牌时没有出现炸弹的概率，那么在阶段与阶段之间应该有如下递推公式：&br&&img src=&///equation?tex=d_%7Bijk%7D%5E%7B%28m%29%7D+%3D+%5Csum+p_%7B%28i%27j%27k%27+%5Crightarrow+ijk%29%7D+%5Ccdot+d_%7Bi%27j%27k%27%7D%5E%7B%28m-1%29%7D& alt=&d_{ijk}^{(m)} = \sum p_{(i'j'k' \rightarrow ijk)} \cdot d_{i'j'k'}^{(m-1)}& eeimg=&1&&&br&这里的&img src=&///equation?tex=%28i%27%2Cj%27%2Ck%27%29& alt=&(i',j',k')& eeimg=&1&&是&img src=&///equation?tex=m-1& alt=&m-1& eeimg=&1&&阶段可以转移到&img src=&///equation?tex=m& alt=&m& eeimg=&1&&阶段&img src=&///equation?tex=%28i%2Cj%2Ck%29& alt=&(i,j,k)& eeimg=&1&&的合法状态，&img src=&///equation?tex=p_%7B%28i%27j%27k%27+%5Crightarrow+ijk%29%7D& alt=&p_{(i'j'k' \rightarrow ijk)}& eeimg=&1&&是其对应的转移概率，再注意考虑好边界条件应该就可以做了。&br&&br&其实你仔细观察会发现，表示阶段这个上标实际上是多余的，在我们重新确定的发牌过程中&img src=&///equation?tex=%28i%2Cj%2Ck%29& alt=&(i,j,k)& eeimg=&1&&本身就足以定义好状态了，所以上面的公式可以重新改写成下面这个最终版：&br&&img src=&///equation?tex=d_%7Bijk%7D+%3D+%5Csum+p_%7B%28i%27j%27k%27+%5Crightarrow+ijk%29%7D+%5Ccdot+d_%7Bi%27j%27k%27%7D& alt=&d_{ijk} = \sum p_{(i'j'k' \rightarrow ijk)} \cdot d_{i'j'k'}& eeimg=&1&&&br&&br&简单写了段C/C++的求解代码：&br&&div class=&highlight&&&pre&&code class=&language-cpp&&&span class=&cp&&#include &iostream&&/span&

斗地主一局中炸弹出现的概率(≈0.5445)确实挺大，下面是我的推导思路(动态规划)：“至少一人有炸弹”与“每个人都没炸弹”互为对立命题，方便起见我们先求“每个人都没炸弹”的概率。假设当三个玩家(A、B、C)的座次选定，一副牌随机打乱发完时，A得到1-17号…
我曾经玩过连续几十盘没有发过王炸，还是似乎发过一盘还是两盘，盘盘都是零零散散的牌，在中级场一下午输了五十万豆，用打麻将的术语就叫全场没胡牌。我感到非常的奇怪，就算是随机的发牌，也不可能几十盘没王炸，基本上把把烂牌。&br&&br&&br&我肯定的一点就是腾讯斗地主的发牌程序是经过了精心设计的，这个算法的目的，就是考虑了维持住玩家的情况下，尽可能的利用欢乐豆然后让大家花钱。考虑到我那次实际上是一步步从系统送的1000豆爬上去的，所以他这么做很合理。一是让你尝甜头，爬到八十万左右的豆确实运气不错，很多好牌。二就是把甜头给你拿走，很多人不干啊，就像富了以后再去过穷生活，怎么过？另一方面，人在连续输的情况下容易失去理智，往往输得更多，就像股票期货市场一样。所以这种算法，他设计的时候，其实考虑了人的心理因素，那么我输得差不多的时候怎么做呢？当然是不服，那就买欢乐豆啊！（不过我是在还有三十多万的时候把斗地主卸载了）。所以我是深深地感受到腾讯真的是做产品的高手，国内的公司做产品没有一个是腾讯的对手。&br&&br&至于写个程序判断是好牌还是差牌不难的，好牌是大牌，连续牌，整齐牌，差牌是小牌，断张，零散牌，然后做一个估值的模型，参数可以通过机器学习的方式获得。&br&&br&在欢乐斗地主这种涉及到玩家花钱的事上，精心研究一个能留住玩家又能最大限度赚钱的算法，我觉得是要花点心思的。算法怎么样对各种因素做决策是关键问题，技术倒是很好实现。楼主说的情况是有可能的，他可能会考虑最近的比赛结果，然后会适当的给你发好牌或者烂牌，俗称boosting。&br&&br&anyway，幸亏输得是欢乐豆。赌博，大抵也是类似的，无论是什么街头游戏还是华尔街的种种，还是卸载客户端吧
