MiniMax engine in PHP
=====================

[](#minimax-engine-in-php)

This library provides easy integration of the MiniMax game decision making algorithm into your game, using a simple interface to separate the algorithm from the game logic.

Usage
-----

[](#usage)

To use this library, first make sure you implement each interface in `lucidtaz\minimax\game`.

Then, simply construct an instance of `lucidtaz\minimax\engine\Engine`, give it the `Player` to act as, and when it is the player's turn, call the `decide()`method. This will result in the `GameState` instance that results after the engine takes its move.

In code:

```
class MyPlayer implements \lucidtaz\minimax\game\Player
{
    ...
}

class MyGameState implements \lucidtaz\minimax\game\GameState
{
    ...
}

$player = new MyPlayer(...);
$engine = new \lucidtaz\minimax\engine\Engine($player);

$gameState = new MyGameState(...);

$newGameState = $engine->decide($gameState);
```

For an example, see the `tests/tictactoe` directory or any of the other sample game implementations in `tests/`.
