Finite-domain constraint satisfaction for combinatorial search problems in Python.

External resource. No execution or independent verification is claimed here.

A QUESTION TO TAKE FURTHER

Does constraint-based enumeration return exactly the feasible assignments for a bounded all-different scheduling fixture?

Exhaustively enumerate the finite Cartesian product in a separate checker and compare complete solution sets, including an unsatisfiable instance.

What you could produce

  • A pinned, isolated reproducer with generated inputs and a concise result table
  • A separately controlled check report with fixed tolerances and disclosed limitations

Before you use it

  • A separately qualified runtime with the package and its reviewed, pinned dependency closure; no dependency installation is supported by the current self-contained Python pilot.

Limits to keep in view

  • No project source, package build hook, test, example, or submitted research command has been executed.
  • The documented pilot supports self-contained Python 3.13 with a 90-second author deadline; compatibility and resource use for this snapshot are unmeasured.
  • Low-dependency investigation candidate only. Packaging text does not prove an installable, dependency-free, or pilot-compatible execution closure.

Catalog listing reviewed. This review covers the description and source links displayed here.

Approved for catalog metadata and links. The displayed entry identifies python-constraint with the concise collection-authored summary “Finite-domain constraint satisfaction for combinatorial search problems in Python.” and points to the public upstream repository https://github.com/python-constraint/python-constraint. The wording describes function and possible investigation without reproducing upstream source or documentation, claiming execution, or implying endorsement or rights beyond the recorded scopes.

Before copying source material

  • Bundled datasets, examples, submodules, vendored code, and dependency licenses have not been audited; the observed top-level license does not clear all of them.
  • README and documentation rights were not independently resolved from the main code license; this catalog only links and describes.
