This package provides some optimization problems using the

[NLPModels.jl](https://github.com/JuliaSmoothOptimizers/NLPModels.jl)

interface. It is similar to to

[OptimizationProblems.jl](https://github.com/JuliaSmoothOptimizers/OptimizationProblems.jl),

except that it's specific for Nonlinear Least Squares, using the subtype

of `AbstractNLSModel`.

This collection currently contains the problems of Moré, Garbow and

Hillstrom [1].

We welcome contributions.

## Install

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

```julia

julia> ]

pkg> add NLSProblems

pkg> test NLSProblems

```

## How to cite

If you use NLSProblems.jl in your work, please cite using the format given in [CITATION.cff](CITATION.cff).
