Authors of CUTEr
CUTEr has been superceded by CUTEst and is no longer supported. Please proceed to the new web site. The following pages are simply provided as a historical record. CUTEr is a versatile testing environment for optimization and linear algebra solvers. The package contains a collection of test problems, along with Fortran 77, Fortran 90/95 and Matlab tools intended to help developers design, compare and improve new and existing solvers.

The test problems provided are written in so-called Standard Input Format (SIF). A decoder to convert from this format into well-defined Fortran 77 and data files is available as a separate package. Once translated, these files may be manipulated to provide tools suitable for testing optimization packages. Ready-to-use interfaces to existing packages, such as MINOS, SNOPT, filterSQP, Knitro, and more, are provided. See the interfaces section for a complete list.

CUTEr is available on a variety of UNIX platforms, including Linux and is designed to be accessible and easily manageable on heterogeneous networks.

New:  An updated version of CUTEr is now available featuring simplified tools and a new Matlab interface with dynamic allocation. This version of CUTEr 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, CUTEr is 100% backward-compatible with earlier versions of CUTE.
