Known Limitations

The engine currently has some weaknesses:

• May miss obvious checkmates
• Can fall into threefold repetition in winning positions
• Basic time management system

These are being actively worked on for future improvements.

Prerequisites

• Bun installed on your machine
• lc0 installed for network conversion

Installation

1. Clone the repository:

   git clone https://github.com/sad-pixel/a0lite-js.git
   cd a0lite-js

2. Install dependencies:

   bun install

3. Convert an LC0 network to ONNX format:

   lc0 leela2onnx --input=<path-to-network-file> --output=<path-to-output-onnx-file>

   Place the resulting ONNX model in the nets directory.

Usage

Run the application using Bun:

bun run index.ts

This starts the application as a UCI engine.
