<longdescription lang="en">
Ceres Solver is a portable C++ library that allows for
modeling and solving large complicated nonlinear least squares
problems. It features:
* automatic differentiation
* robust loss functions
* local parameterizations
* threaded Jacobian evaluators and linear solvers
* Levenberg-Marquardt and Dogleg (Powell, Subspace) solvers
* Dense QR and Cholesky factorization (using Eigen) for small problems
* Sparse Cholesky factorization (using SuiteSparse) for large sparse
problems
* Specialized solvers for bundle adjustment problems in computer vision
* Iterative linear solvers for general sparse and bundle
adjustment problems
