Quick hobby hack to made a march madness bracket simulator as I was too lazy to fill one out online. It's probably terrible but was fun to put together. Utilizes the openai function calling to extract a single winner from provided matchups as the tournament progresses. Can also run a quick random or seed based decider. For AI decisions, you can input custom instructions such as "pick teams with a dog mascot".

Put this app behind fastapi and hosted a React page!

The new frontend provides a cool inferface for simulating the March Madness tournament. It communicates with Python using fastAPI and websockets to run the simulations and display the results in real-time.

For more details about the frontend implementation, please refer to the frontend README.

• Realistic Simulations: The simulator uses advanced decision-making functions to determine the winner of each matchup, taking into account factors such as team rankings, historical performance, and more.
• Multiple Decision Functions: Choose from three different decision functions to determine the outcome of each game: AI-powered decisions using OpenAI's GPT-3.5, seed-based decisions, or random winner selection.
• Detailed Bracket Visualization: The simulator provides a clear and concise representation of the bracket, displaying the progress of the tournament from the Round of 64 to the Championship game.
• Customizable Initial Bracket: Load your own initial bracket data from a JSON file to simulate different tournament scenarios.
• State Persistence: Save and load the current state of the tournament, allowing you to resume the simulation from where you left off.

To get started with the NCAA March Madness Bracket Simulator, follow these steps:

1. Clone the repository: git clone https://github.com/cipher982/march-madness-llm

2. Install the required dependencies: pip install -r requirements.tx

3. Obtain an API key from OpenAI and set it as an environment variable: export OPENAI_API_KEY=your_api_key_here

4. Run the simulator: python simulator.py

5. Customize the simulation by providing command-line arguments:

   • --decider: Choose the decision function for simulating games (options: "ai", "seed", "random", default: "seed").
   • --current-state: Provide a JSON file containing the current state of the bracket to resume the simulation. current_state.json is the file I try to keep updated, including the teams, matchups, rounds and winners. At least as current as I give the effort to update.

The project consists of three main files:

• main.py: The entry point of the application. It sets up the argument parser, creates the bracket, and runs the simulation.
• deciders.py: Contains the decision functions used to determine the winner of each matchup, including the AI-powered decision using OpenAI's GPT-3.5.
• bracket.py: Defines the classes for the bracket structure, including Team, Matchup, Round, Region, and Bracket. It also provides methods for loading initial data, updating the bracket state, and visualizing the bracket.
