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.
