There is a Julia version of this code, [StochasticSeriesExpansion.jl](https://github.com/lukas-weber/StochasticSeriesExpansion.jl), which is better documented, more user-friendly and also slightly faster than this C++ version. It is therefore recommended to use the Julia code.

This repository is provided without maintenance or support, solely for the interest of the community. If you still decide to use it for some research, kindly cite the DOI.
