This repository provides a solver of pymanopt, which is an implementation of the Hybrid Riemannian conjugate gradient method. This implementation is based on the treatise,

H. Sakai, H. Iiduka: Hybrid Riemannian Conjugate Gradient Methods with Global ConvergenceProperties, (submitted)

All numerical examples presented in the paper are used this implementation. Our implementation is the modification of pymanopt.solver.ConjugateGradient.

The experiments follow the examples of pymanopt.
