SAL Home NUMERICS Optimization


The Constrained and Unconstrained Testing Environment (CUTE) is a suite of Fortran subroutines, scripts and test problems for linear and nonlinear optimization. Its purpose is to:

  • provide a way to explore an extensive collection of problems (over 800 different test problems to date);
  • provide a way to compare existing packages;
  • provide a way to use a large test problem collection with new packages;
  • provide motivation for building a meaningful set of new interesting test problems;
  • provide ways to manage and update the system efficiently; and
  • do all the above on a variety of popular platforms.
