Constraint Programming (CP) is a powerful paradigm for solving complex combinatorial problems across a wide range of domains.
Over the years, many solvers and tools have been developed, but their interoperability remains limited.

TOOTATIS addresses this challenge by offering a modular ecosystem that fosters integration, experimentation, and ease of use across different solvers, formats, and languages.

Initially centered around the Universe library, TOOTATIS has evolved to encompass a broader collection of complementary tools for modeling, solving, and analyzing constraint-based problems.

Our toolset includes solutions for:

  • πŸ“¦ Solver installation and management
  • πŸ“Š Experimentation and performance analysis
  • πŸ› οΈ Solver configuration standardization
  • πŸ”— Integration with modern development environments (e.g., VSCode)
