XCut 1.0.0

!!! Important: This project is in development. It may contain bugs or usability issues. Please check the offical repository on Gitlab for the current release version or to report any issues.

This repository contains the release version of XCut. XCut is a novel solver for the normalized cut problem on graphs based on expander decomposition and the expander hierarchy. To the best of our knowledege, this project is the first implementation of the expander hierarchy.

Building

You need to have CMake installed, configure a build type from CMakePresets.json and build the executable. All dependencies are fetched automatically by CMake.

Running

XCut supports mtx files, files in the chaco format and edge list files. If the extension of the file is correct it should automatically read the file correctly. See the usage guide provided when invoking xcut.

Bugs

XCut is an in development project and interfaces may not be stable yet and subject to change. In case you find any bugs, please create an issue in this repository.

Future features

We are planning to implement a number of additional features in XCut, such as parallelization, additional cut objectives, etc.
