TRIQS/SOM: Stochastic Optimization Method for Analytic Continuation

Copyright (C) 2016-2025 Igor Krivenko

This program is an optimized implementation of an analytic continuation method proposed by Andrey S. Mishchenko. A detailed description of the method can be found in http://www.cond-mat.de/events/correl12/manuscripts/mishchenko.pdf.

SOM 2.x offers new features, including the more advanced SOCC (stochastic optimization with consistent constraints) analytic continuation protocol.

SOM uses the TRIQS library version 3.2.x or 3.3.x. The TRIQS website is under https://triqs.github.io/triqs/. Start there to learn about TRIQS.

Legacy SOM versions 1.x are based on TRIQS 1.4.2. The 1.x source code is still available on the 1.x branch; Its respective documentation web-site was moved to https://krivenko.github.io/som1.

Installation

SOM can be installed using the conda package manager or built from source either manually or by means of the EasyBuild HPC software management framework.

We also offer prebuilt Docker images.

Please, refer to http://krivenko.github.io/som/install.html or doc/install.rst in the source code tree for the detailed installation instructions.
