SifDec is a decoder. It tranlates test problems, written
in so-called Standard Input Format
into well-defined Fortran 77 and data files. Once
translated, these files may be manipulated to provide tools
suitable for testing optimization packages.
The SIF is a superset of the
modelling language. SifDec can therefore decode any Linear
Program coded in MPS format.
SifDec used to be part of, and has been extensively used with,
testing environment and is now a vital component of the
environment, which includes ready-to-use interfaces to existing
packages, such as
but could also serve different purposes.
Novel features include the ability to decode parameterized test
problems, and to prepare the decoded problem for packages using
automatic differentiation techniques.
SifDec is now distributed as a separate package for both convenience
reasons and to encourage consistent use in conjunction with other
software and packages.
SifDec is available on a variety of
UNIX platforms, including Linux
and is designed to be accessible and easily manageable on heterogeneous
New: An updated version of SifDec
is now available featuring simplified tools.
This version of SifDec supersedes the
current version. Users are advised to head to the
development website and
migrate to the new tools.
New: CUTEr and SifDec are now available
on MAC OS-X platforms.
Except for DOS and VAX/VMS, SifDec is 100% backward-compatible with
earlier versions of
