Я создал несколько фиктивных кодов, которые помогут вам понять, как это сделать. Код вообще не оптимизирован, но вы понимаете, как это сделать, линейно.
prob_res <- matrix(round(runif(64),2), 8, 8)
prob_res[lower.tri(prob_res, diag = TRUE)] <- 0
prob_res <- as.data.frame(prob_res)
colnames(prob_res) <- 1:8
rownames(prob_res) <- 1:8
prob_res
## Total number of combinations
posscombi<-t(combn(1:8, 2))
## This function gives you winners of the match with n repetitionmatches against every other team possible combination of teams.
## It "reproduces" like the whole league assuming winning probabilities are static.
League <- function(repetitionMatches, posscomb , prob_res)
{
TotalVect<-integer(0)
for(i in 1:nrow(posscomb)){
pair <- posscomb[i,]
Vect<-sample(pair,
size = repetitionMatches,
prob = c(prob_res[pair[1], pair[2]], 1-prob_res[pair[1], pair[2]]),
replace = TRUE)
TotalVect <- c(TotalVect, Vect)
}
return(table(TotalVect))
}
Result<-League(100,posscomb = posscombi, prob_res= prob_res)
Myorder<-order(Result)
### Quarters
pair1<- c(names(Result)[Myorder[c(1,8)]])
pair2<- c(names(Result)[Myorder[c(2,7)]])
pair3<- c(names(Result)[Myorder[c(3,6)]])
pair4<- c(names(Result)[Myorder[c(4,5)]])
## This function gives you the results to n matches (being 3 in the example)
PlayMatch<-function(pairs, numMatches){
Res <-sample(pairs, size = numMatches,
prob = c(prob_res[pairs[1], pairs[2]], 1-prob_res[pairs[1], pairs[2]]),
replace = TRUE)
return(table(Res))
}
# Results of the matches
winner1<-PlayMatch(pairs = pair1, 3)
winner2<-PlayMatch(pairs = pair2, 3)
winner3<-PlayMatch(pairs = pair3, 3)
winner4<-PlayMatch(pairs = pair4, 3)
## Semis
#Choosing the winning teams
pair1<- c(names(winner1)[which.max(winner1)],names(winner2)[which.max(winner2)])
pair2<- c(names(winner3)[which.max(winner3)],names(winner4)[which.max(winner4)])
winner1<-PlayMatch(pairs = pair1, 3)
winner2<-PlayMatch(pairs = pair2, 3)
## Final
# Same as before
pair1<- c(names(winner1)[which.max(winner1)],names(winner2)[which.max(winner2)])
winner1<-PlayMatch(pairs = pair1, 3)
paste0( "team ",names(winner1)[which.max(winner1)], " is the winner!")
