Welcome to the world of EasyAI, a powerful Python framework designed specifically for two-player abstract games like Tic Tac Toe, Connect 4, and Reversi. In this article, we will guide you through the installation process, how to set up a game, and even how to employ artificial intelligence to enhance your gaming experience!

Installation Steps

Before diving into the gaming aspect, let’s get EasyAI installed on your system:

• If you have pip installed, run the following command in your terminal:

sudo pip install easyAI

• If you don’t have pip, you can download the source code from Github, unzip it into a folder, and execute:

sudo python setup.py install

• Lastly, you will also need to install Numpy for running some examples. This can be done with:

sudo pip install numpy

Creating a Game of Bones

Now that you have EasyAI installed, let’s define the rules of a game and start a match against the AI. Think of this as building a simple board game, where you set the stage and rules before diving into the action.

Below is an example of how to create a game of bones where two players take turns removing 1 to 3 bones from a pile until one player loses by taking the last bone:

from easyAI import TwoPlayerGame, Human_Player, AI_Player, Negamax

class GameOfBones(TwoPlayerGame):
    def __init__(self, players=None):
        self.players = players
        self.pile = 20  # Start with 20 bones
        self.current_player = 1  # Player 1 starts

    def possible_moves(self):
        return [1, 2, 3]

    def make_move(self, move):
        self.pile -= int(move)  # Remove bones

    def win(self):
        return self.pile == 0  # Check if opponent took the last bone

    def is_over(self):
        return self.win()  # Game stops when someone wins

    def show(self):
        print("%d bones left in the pile" % self.pile)

    def scoring(self):
        return 100 if self.win() else 0  # Score for the AI

# Start a match
ai = Negamax(13)  # AI thinks 13 moves ahead
game = GameOfBones([Human_Player(), AI_Player(ai)])
history = game.play()

Understanding the Code with an Analogy

Imagine you are an architect laying out the blueprint for a new game. Each segment of code serves as a building block ensuring that your game functions correctly:

• Class Definition: The GameOfBones is the architectural blueprint where you define the structure of the game.
• Pile of Bones: The pile itself (20 bones) can be likened to the foundational material of a building; it determines how the game will progress.
• Possible Moves: Each possible move represents options available to players, just like openings in a design that allow for different construction pathways.
• Scoring: The scoring method ensures players understand the outcomes of their actions, similar to grading a completed structure based on its purpose.

Solving the Game

To take your game to the next level, let’s see how we can solve it: Determine the optimal moves that lead to a guaranteed win!

from easyAI import solve_with_iterative_deepening

r, d, m = solve_with_iterative_deepening(
    game=GameOfBones(),
    ai_depths=range(2, 20),
    win_score=100
)

Here, r indicates if the first player can force a win, d gives the depth of moves required, and m shows how many bones to remove first. This simplifies the process of determining the outcome, creating a strategic approach akin to a chess player contemplating their next move.

Troubleshooting Tips

If you encounter any issues during installation or while using EasyAI, consider these troubleshooting ideas:

• Ensure pip is installed and up-to-date.
• Check that your Python and Numpy installations are configured correctly.
• Refer to the EasyAI documentation available here for detailed explanations.
• If you experience technical challenges, feel free to discuss them on Github.
