STAG is a C++ library providing efficient spectral algorithms for the analysis of massive graphs. The development of STAG is part of He Sun's Fellowship titled "Efficient Spectral Algorithms for Massive and Dynamic Graphs", which is funded by the UK Engineering and Physical Sciences Research Council (EPSRC, EP/T00729X/1). The team for developing STAG consists of Peter Macgregor and He Sun.
The project is under active development; more information and documentation can be found here, and our website.
