Hey there Wahyu, The conjugate gradient method is indeed not implemented in ensmallen. But, I am not sure it is appropriate---to my understanding, the CG method is specific to solving a system of linear equations. So, I am not sure how it could be implemented as, e.g., a generic optimizer for differentiable functions. But, maybe there is something I overlooked? Also, if you are indeed just aiming to use CG to solve a system of linear equations, you may be able to rely on Armadillo support instead (which may or may not use the conjugate gradient method under the hood---I'm not sure). If you like, I'd be happy to try and take a look at your proposal in the next day or two and leave some comments. Thanks!
