下面是一个用Clojure编写的计算德州扑克6人桌初始手牌胜率的程序,它不考虑公共牌:
```
(defn all-hands []
(let [ranks "AKQJT98765432"
suits "shdc"]
(for [r1 ranks
r2 ranks
:when (not= r1 r2)
s1 suits
s2 suits]
(list (str r1 s1) (str r2 s2)))))
(defn score [cards]
(let [values (sort (map #(if (= (first %) \1) 14 (int (first %))) cards))
suits (frequencies (map #(second %) cards))
flush? (some #(>= % 5) suits)
straight? (let [consec (apply max (map #(apply - %) (partition-all 2 1 (conj values 15))))] (= consec 4))
wheel? (= (sort values) [2 3 4 5 14])]
(cond
flush? (if straight? (if (= (apply min values) 10) 10 (+ 900 (last values))) (+ 600 (apply max values)))
straight? (if wheel? 5 (+ 500 (last values)))
:else (if (= (apply max (vals (frequencies values))) 4)
(+ 700 (first (keep #(if (= 4 (last %)) (first %)) (frequencies values))))
(if (= (apply max (vals (frequencies values))) 3)
(if (= (count (filter #(= 2 (last %)) (frequencies values))) 1)
(+ 400 (first (keep #(if (= 3 (last %)) (first %)) (frequencies values))))
(+ 300 (first (keep #(if (= 3 (last %)) (first %)) (frequencies values))) (apply max (keep #(if (= 2 (last %)) (first %)) (frequencies values)))))
(if (= (count (filter #(= 2 (last %)) (frequencies values))) 2)
(+ 200 (apply max (keep #(if (= 2 (last %)) (first %)) (frequencies values))) (apply min (keep #(if (= 2 (last %)) (first %)) (frequencies values))) (first (keep #(if (= 1 (last %)) (first %)) (frequencies values))))
(+ 100 (apply max values))))))))
(defn win-probability [my-hand]
(let [opponent-hands (remove #{my-hand} (all-hands))]
(loop [wins 0
ties 0
opponents opponent-hands]
(if (empty? opponents)
(/ (+ wins (* ties 0.5)) (count opponent-hands))
(let [opponent-hand (first opponents)
my-score (score my-hand)
opponent-score (score opponent-hand)]
(cond
(> my-score opponent-score) (recur (inc wins) ties (rest opponents))
(= my-score opponent-score) (recur wins (inc ties) (rest opponents))
:else (recur wins ties (rest opponents))))))))
(defn calculate-win-probabilities []
(let [hands (all-hands)]
(for [hand hands]
(let [win-prob (win-probability hand)]
(println (str "Hand: " hand ", Win Probability: " win-prob))))))
(calculate-win-probabilities)
```
这个程序定义了三个函数:all-hands、score和win-probability。其中,all-hands函数生成了所有可能的手牌,score函数计算给定手牌的得分,win-probability函数计算给定手牌的胜率。最后,calculate-win-probabilities函数生成了所有手牌的胜率列表,并打印输出。
你可以在Clojure的REPL环境中加载或定义这个程序,并调用calculate-win-probabilities函数来计算所有初始手牌的胜率。注意,这个程序只考虑了初始手牌,没有考虑公共牌。
