minilsap 0.1.1

Python module to solve the linear sum assignment problem (LSAP) efficiently

minilsap

A Python module to solve the linear sum assignment problem (LSAP) efficiently. Extracted from SciPy, without significant modifications.

This module is useful in cases when you need an efficient LSAP solver but you do not want to depend on the full SciPy library.

Currently, the module depends on NumPy for array management. This may be relaxed in the future if Python's stable API gets extended with functions to manage Python buffer objects.
