Is it possible to create an unbeatable Tic Tac Toe agent which doesn't enumerate all the cases?
I'm sure it is, and this is my attempt
- There are three ways to play with this code
- Just the Agent (as a node module dependency)
- Using the whole App
- Via the deployed API
$ mkdir ttt-client
$ cd ttt-client
$ npm init
# Complete the init
Install the tictactoe-agent
$ npm install tictactoe-agent --save
Add: index.js
var TicTacToe = require('tictactoe-agent');
var model = new TicTacToe.Model('---------', 'X');
var recommendation = model.getRecommendation();
console.log(recommendation.index);
// Will Print out the recommended move
tictactoe is a command line node.js application which takes the game state and current player 'X' or 'O' as parameters as follows:
$ git clone git@github.com:stujo/javascript-node-tic-tac-toe.git
$ cd javascript-node-tic-tac-toe
$ ./tictactoe --------- x

* Recommendation for X is 2 (Score: 3)

The board state is provided as a string with hyphens denoting empty spots, and X or O marking the take spots
The spots on the board are numbered as follows:
#####
#012#
#345#
#678#
#####
The optional fourth parameter debug prints out debugging info:
$ ./tictactoe --------- x debug
