QuantumOX is a high-performance, GPLv3-licensed Tic-Tac-Toe engine implemented in C++. It implements the UTTTI (Universal Tic Tac Toe Interface) — a protocol inspired by UCI — and is designed to handle a wide variety of board geometries (2D and 3D) and rule variants at scale.
Built with attention to search performance and extensibility, QuantumOX integrates advanced search techniques (iterative deepening, alpha-beta pruning, quiescence, transposition tables, and selective extensions) together with pragmatic engineering choices that make it fast and robust across small boards (3x3) and larger multi-dimensional variants (3x3x3, 4x4x4, up to 15x15 grids).
Note: QuantumOX is a command-line / engine component only — it does not include a graphical user interface. A GUI that supports UTTTI is under active development by the author and will be published separately.
- UTTTI-compatible engine protocol for programmatic control and integration.
- Highly optimized search with iterative deepening, quiescence search, and selective extensions.
- Configurable hash table (transposition table) and multi-threaded search support.
- Advanced move ordering heuristics (killer, history, TT, PV guidance) and per-iteration diagnostics in the info output.
- Support for multiple grid sizes and dimensions (2D and 3D variants).
- Portable C++ codebase with a Makefile for Unix-like systems.
This distribution includes the following top-level items:
-
README — this document.
-
LICENSE — the project's GNU GPLv3 license.
-
src — source tree containing the engine implementation and a Makefile.
QuantumOX supports both 32-bit and 64-bit targets. The build system is intentionally minimal and portable; it uses a Makefile located in src/.
To build on Unix-like systems (Linux, macOS with developer tools), run:
cd src
make -j buildRun make help inside src/ for additional build targets and cross-platform hints. The default targets are tuned for common Intel/AMD CPUs; adjust CXXFLAGS in the Makefile if you need compiler-specific tuning.
Contributions, bug reports, and feature requests are welcome. Please follow the repository Contributing Guide for the contribution process and coding guidelines.
