%description
A self-contained native engine (a C interface over C++ host logic) for
stochastic actor-oriented models (the model family of 'RSiena'),
exponential random graph models (cross-sectional, temporal, and separable
temporal), and models for binary actor attributes, callable from R without
a Python runtime. The CRAN build is CPU-only (C++17, multi-threaded with
'OpenMP'); a 'CUDA' backend implements the same interface and is built
separately from source. The data preparation, host statistics ('RSiena'
Appendix B conventions), and moment targets are validated bit-for-bit
against the reference implementation and reproduce 'RSiena' targets on
public datasets to machine precision; the estimators match 'RSiena',
'ergm', 'btergm', and 'tergm' on public benchmark models. The
method-of-moments estimator returns standard fit objects with the
simulated networks on request, and the simulator also plugs into the
unmodified 'RSiena' estimator.
