How to Access Variable Values After Each Iteration in Ceres?

[Shengkai Guo]

Hi!!!!!!!!!!!

I am using Ceres (version 2.1.0) to solve a multivariable optimization problem, and I need to record the values of the optimization variables (e.g., x, not objective function values f(x) ) after each iteration. I’ve tried custom callbacks and using Evaluate(), but I’m only able to get the initial values or face other issues.

Is there a recommended way to retrieve the variable values after each iteration? Any guidance or suggestions would be greatly appreciated!

Thank you!
