This package provides a collection of optimization problems in JuMP and ADNLPModels syntax.

OptimizationProblems can be installed and tested through the Julia package manager:

julia> ]
pkg> add OptimizationProblems
pkg> test OptimizationProblems

You can obtain the list of problems currently defined with names(OptimizationProblems.PureJuMP). The first symbol in the list is :PureJuMP itself–the name of the module.

Currently, only a few unconstrained problems are implemented. Some are available in variable size.

This module is particularly useful in conjunction with NLPModels to facilitate evaluating objective, constraints and their derivatives.

Please open pull requests to submit new problems! When submitting a problem, please pay particular attention to the documentation. We would like to gather as much information as possible on the provenance of problems. The documentation Contributing provides general guidelines on how to suggest new problems.

If you use OptimizationProblems.jl in your work, please cite using the format given in CITATION.bib.
