%description
    Ceres Solver is an open source C++ library for modeling and solving
    large, complicated optimization problems. It can be used to solve
    Non-linear Least Squares problems with bounds constraints and
    general unconstrained optimization problems. It is a mature, feature
    rich, and performant library that has been used in production at
    Google since 2010.
