Top 5 Conjugate Gradient Open-Source Projects

ceres-solver

8 3,589 8.3 C++

A large scale non-linear optimization library

Project mention: The Elements of Differentiable Programming | news.ycombinator.com | 2024-03-22

I can't reply to the guy saying julia is the only one. But there are others.
Ceres uses dual numbers
https://github.com/ceres-solver/ceres-solver/blob/master/inc...
This library from google is used everywhere in robotics, so it's hardly some backwater little side project.
So does c++ autodiff

DFTQuantumDot

3 22 5.4 C++

Density Functional Theory with plane waves basis, applied on a 'quantum dot'. Volumetric visualization of orbitals with VTK

Project mention: Help making plot for experiment | /r/cpp_questions | 2023-06-02

In this one I used VTK to plot 3D data: https://github.com/aromanro/DFTQuantumDot
