Hi,

I am wondering if we can use Gradient Descent in Ceres-Solver? 

the reason why I am asking is that LM and Gauss-Newthon-like optimizers don't fit my problem. Therefore I am wondering if there is some option to directly set to gradient descent optimizer?

many thanks in advance,
Mengkun

Hi, Mengkun

You might want to take a look at http://ceres-solver.org/gradient_solver.html .
It supports minimization of abstract (not necessarily least-squares) functions using gradient descent and (L)BFGS.
