计算德州扑克6人游戏中不同手牌的获胜概率需要考虑所有可能的手牌组合与公共牌的组合情况。以下是一个R代码示例,用于计算不同手牌的获胜概率:
```R
# 定义扑克牌
suits <- c("hearts", "diamonds", "clubs", "spades")
values <- c("A", "K", "Q", "J", "10", "9", "8", "7", "6", "5", "4", "3", "2")
cards <- expand.grid(value=values, suit=suits)
# 定义一副牌
deck <- paste(cards$value, "of", cards$suit)
# 定义所有可能的手牌组合
all_hands <- combn(deck, 2)
# 定义公共牌
board <- c("2h", "5h", "9c", "10d", "Qh")
# 定义计算每种手牌组合胜率的函数
calculate_win_rate <- function(hand, board, deck) {
# 生成所有可能的手牌组合
hand_combinations <- combn(setdiff(deck, c(hand, board)), 2)
# 计算每种手牌组合的胜率
wins <- 0
total <- ncol(hand_combinations)
for (i in 1:total) {
opponent_hand <- hand_combinations[,i]
all_cards <- c(hand, board, opponent_hand)
player_score <- PokerHand::score_hand(all_cards[1:2], all_cards[3:7])
opponent_score <- PokerHand::score_hand(opponent_hand, all_cards[3:7])
if (player_score > opponent_score) {
wins <- wins + 1
}
}
# 返回胜率
return(wins / total)
}
# 计算不同手牌获胜概率
win_rates <- matrix(NA, nrow=nrow(all_hands), ncol=1)
for (i in 1:nrow(all_hands)) {
hand <- all_hands[,i]
win_rates[i] <- calculate_win_rate(hand, board, deck)
}
# 输出结果
result <- data.frame(hand1=all_hands[1,], hand2=all_hands[2,], win_rate=win_rates)
result <- result[order(result$win_rate, decreasing=TRUE),]
head(result)
```
这段代码用到了PokerHand包来计算牌型得分。输出结果将显示不同手牌的获胜概率,并按照获胜概率从高到低排序。注意,这只是一个简单的示例代码,实际应用中需要考虑更多因素,如对手的行为模式和策略等。
