OptProblems.jl

Nonlinear optimization repository in Julia.

Usage

You must now the problem name to call a function with it's name. Install this package and use with

julia> Pkg.clone("https://github.com/ufpr-opt/OptProblems.jl")
julia> using OptProblems

Now obtain function definitions with

julia> f, g, H, x0 = OptProblems.rosenbrock()
julia> #OR
julia> f, g, H, x0 = getProblem("rosenbrock")
julia> #OR
julia> f, g, H, x0 = getProblem(:rosenbrock)

The string version is case insensitive.

Contributing

To contribute a problem, create a file for it, then include the file on OptProblems.jl. The file and the function must have the same name. Use a comprehensive naming, and if necessary, add an alias for it. See for instance, Rosenbrock's problem. We chose to name the function rosenbrock, but CUTEst users might try to call rosenbr, which must also be accepted. All function names should be lowercase and use _ (underscore) to separate words when necessary.

After that, send a pull request or e-mail the patch to [email protected].

Objective

This repository will be used mostly as exercise for students, or as a quick test for algorithms. For a serious optimization repository in Julia, consider CUTEst.jl.
