+python3-lap (Linear Assignment Problem solver LAPJV/LAPMOD).
+
+lap is a linear assignment problem solver using Jonker-Volgenant
+algorithm for dense LAPJV¹ or sparse LAPMOD² matrices. Both algorithms
+are implemented from scratch based solely on the papers¹˒² and the
+public domain Pascal implementation provided by A. Volgenant³. The
+LAPMOD implementation seems to be faster than the LAPJV implementation
+for matrices with a side of more than ~5000 and with less than 50%
+finite coefficients.
+
+NOTE: While python3-numpy will build without it I highly suggest
+ installing OpenBLAS before building numpy. I would add it to the
+ REQUIRES for python3-lap but it will not be in the proper order
+ for numpy to build against OpenBLAS.
