A Julia package for non-smooth optimization algorithms.

This package provides algorithms for the minimization of objective functions

that include non-smooth terms, such as constraints or non-differentiable penalties.

Implemented algorithms include:

- (Fast) Proximal gradient methods

- Douglas-Rachford splitting

- Three-term splitting

- Primal-dual splitting algorithms

- Newton-type methods

Check out [this section](https://juliafirstorder.github.io/ProximalAlgorithms.jl/stable/guide/implemented_algorithms/) for an overview of the available algorithms.

Algorithms rely on:

- [DifferentiationInterface.jl](https://github.com/gdalle/DifferentiationInterface.jl) for automatic differentiation (but you can easily bring your own gradients)

- the [ProximalCore API](https://github.com/JuliaFirstOrder/ProximalCore.jl) for proximal mappings, projections, etc, to handle non-differentiable terms (see for example [ProximalOperators](https://github.com/JuliaFirstOrder/ProximalOperators.jl) for an extensive collection of functions).

## Citing

If you use any of the algorithms from ProximalAlgorithms in your research, you are kindly asked to cite the relevant bibliography.

Please check [this section of the manual](https://juliafirstorder.github.io/ProximalAlgorithms.jl/stable/guide/implemented_algorithms/) for algorithm-specific references.

## Contributing

Contributions are welcome in the form of [issues notification](https://github.com/JuliaFirstOrder/ProximalAlgorithms.jl/issues) or [pull requests](https://github.com/JuliaFirstOrder/ProximalAlgorithms.jl/pulls). We recommend looking at already implemented algorithms to get inspiration on how to structure new ones.
