This is the wepage for the permanent computation package. This contain a Fortran package in both a serial and
several parallel versions, using either OpenMP or MPI for prallelisation. We also include a Mathematica implementation
of the permanent for general matrices which is faster than the one included in Mathematica, and a Mathematica
implementation of the fast method for matrices of linited bandwidth.
Note: Some users have had problems downloading the packages using Firefox, but other browsers then worked as they should.
The source code of the Fortran package Version 2.0 as a gzipped tar-archive.
We also have an implementation for Mathematica
Version 2.0 which is faster than Mathenaticas own permanent function,
and includes the linear time version for matrices with limited bandwidth.
The package is free to use as long as this paper is cited in any resulting publications
Questions regarding the code should be
directed to Per Håkan Lundow
