Opengm is a c++ template library for discrete factor graph models and distributive operations on these models.

it includes state-of-the-art optimization and inference algorithms beyond message passing. opengm handles large models efficiently, is modular and extendible. the graphical model data structure, inference algorithms and different encodings of functions inter-operate through well-defined interfaces. the binary opengm file format is based on the hdf5 standard and incorporates user extensions automatically.

this package contains the api documentation for the opengm library.
