least-squares-cpp/0.3.0+1

A single header-only library for least squares optimization.

License

least-squares-cpp is a header-only C++ library for unconstrained non-linear least squares optimization using the Eigen3 library.

It provides convenient and configurable access to the following fitting algorithms:

Gradient Descent
Gauss Newton
Levenberg Marquardt

Convergence and runtime behaviour can be parametrized using advanced newton step refinement operators such as line searching or trust region methods.

Barzilai-Borwein Method
Armijo Backtracking
Wolfe Backtracking
Powell's Dogleg Method
