CUTEstProblem Class Reference

#include <alpaqa/interop/cutest/CUTEstLoader.hpp>

Detailed Description

Wrapper for CUTEst problems loaded from an external shared library.

Warning

The lifetime of the wrapper should be at least as long as the lifetime of the CUTEstProblem::problem member. Do not make a copy of the problem that could outlive the wrapper.

Examples

CUTEst/Rosenbrock/main.cpp.

Definition at line 16 of file CUTEstLoader.hpp.
