Design goals

• Simplicity / Clearness
• Correctness
• Simple interfacing with Vita

Purpose

• To establish a flexible test-bed for Artificial Intelligence / Machine Learning techniques
• Easy understanding of a not-so-trivial implementation

Features

• 10x12 mailbox board representation (piece type and colour encoding)
• Principal Variation Search with aspiration search
• Quiescence search
• MVV-LVA, killer moves, history heuristics
• Evaluation based on material, piece square tables

Build requirements

A modern C++ compiler and cmake (https://cmake.org/).

Just type:

cd testudo/src
mkdir -p build
cd build
cmake ..
make

All the output files will be stored in subdirectories of build/ (out of source builds).

To suggest a specific compiler you can write:

CXX=clang++ cmake ..
