Ceres-solver

Nonlinear least squares minimizer

Ceres Solver is an open source C++ library for modeling and solving large, complicated optimization problems. It is a feature rich, mature and performant library which has been used in production at Google since 2010. Ceres Solver can solve two kinds of problems.

1. Non-linear Least Squares problems with bounds constraints.
2. General unconstrained optimization problems.
