Wize

Wize UCI Chess Engine with Multithreading and NNUE Stockfish Evaluation Wize, a C++ UCI-compliant chess engine, integrates a neural network (NNUE) for accurate evaluation and employs a range of advanced search techniques like LazySMP and Multithreading within Alpha-Beta framework, Wize strives to be a top-tier engine but also serves as a valuable resource for developers to enhance their own chess engines.

Requirements

• Wize software requires GCC(GNU Compiler Collection) or CLang, C++ version: CXX >= C++17 !
• It is recommended that the terminal uses a TrueType Font (ttf), Consolas and other monospaced fonts are recommended for the best user experience [Unicode characters and ANSI escape code] (However, most engines are linked directly to the GUI and don't really need to interact with the terminal).

Installation/Usage

Clone the repository:

$ git clone https://github.com/yanpuri/Wize.git

Then, in the directory:

$ cd Wize\Wize
$ make
$ Wize.exe

Run the generated .exe file in the install dir.

• How to work the engine? The UCI (Universal Chess Interface) serves as a widely adopted protocol for interacting with a chess engine and is the preferred method for communication in graphical user interfaces (GUIs) and chess-related tools. The guidelines are outlined in the UCI protocol, which can be accessed and referenced at this link http://page.mi.fu-berlin.de/block/uci.htm
