Regularization Methods for HVIs

This repository contains a hierarchical solver packaged for Python. The solver is aimed at variational inequalities defined over the solution set of a monotone inclusion problem. The problem setting and the employed algorithm are described in [1].

Installation

The package is available through pip, and may be installed via:

pip install Regularization-Methods-for-HVIs

If running the package locally, you can install it using:

pip install .

Examples

Examples may in found in the /examples directory of the repository. These examples additionally constitute the plots generated in the paper [1].
