Play and learn Tic-Tac-Toe Game on R
Install from CRAN
install.packages("tictactoe")Or you may install the recent development version from github
devtools::install_github("kota7/tictactoe")To use,
library(tictactoe)You can play tic-tac-toe on R console.
ttt(ttt_human(), ttt_ai())This would give you a prompt as below.
A B C
------
1| . . .
2| . . .
3| . . .
Player 1 (no name) to play
choose move (e.g. A1) > Type a move, then the oppoenet will respond. To finish the game in the middle, type “exit”.
The default AI player is very week (in fact, he plays randomly). To
play against a more sophisticated player, set the level
argument (from 0 (weekest) to 5 (strongest)).
ttt(ttt_human(), ttt_ai(level = 4))You may play as the second mover by
ttt(ttt_ai(), ttt_human()). You may watch games between AI
players by ttt(ttt_ai(), ttt_ai()).
To conduct a large scale simulation between AI players, use
ttt_simulate function. The code below conducts 100
simulation games between random AIs. The result 0, 1, and 2 indicate
draw, won by player 1, and won by player 2 respectively.
res <- ttt_simulate(ttt_ai(), ttt_ai(), N = 100, verbose = FALSE)
prop.table(table(res))
#> res
#> 0 1 2
#> 0.13 0.57 0.30Q-learning is implemented to train AI players. The code below trains a random AI through Q-learninig of 500 episodes.
p <- ttt_ai()
o <- ttt_qlearn(p, N = 500, verbose = FALSE)Now this player is much stronger than the random player.
res <- ttt_simulate(ttt_ai(), p, N = 100, verbose = FALSE)
prop.table(table(res))
#> res
#> 0 1 2
#> 0.15 0.25 0.60These binaries (installable software) and packages are in development.
