HiReCS - High Resolution Hierarchical Clustering with Stable State

HiReCS is a C++ clustering library for the multi-scale hierarchical community structure discovery with crisp overlaps in large evolving networks having nearly linear computational complexity.
See details in http://www.lumais.com/hirecs, documentation and datasets in http://goo.gl/C4gHH0
API Manual: http://www.lumais.com/doxy/hirecs/index.html
Releases: https://github.com/XI-lab/hirecs/releases

WARNING The library is under development now, it currently has issues with datasets processing of the size more than 100 000 links.
Currently it forms excellent root level (top-level, coarse-grained) clusters, but might have issues with the underlying levels of the hierarchy.
If you find any issues, please submit them here.

Execution Example

<kbd>$ ./hirecs -oje dataovp/pentagon.hig</kbd>

Note: the binaries are located in bin/Release/, target OS: Linux Ubuntu 14.04 x64 (ask me if you need another target architecture, the code is crossplatform).
