There is already a functioning Julia wrapper for LBFGSB: https://github.com/Gnimuc/LBFGSB.jl, which is the basis of the lbfgsb.f used in `scipy.optimize`. Note that `scipy.optimize` uses a modified ve…

It would be great for Ceres to support bound constraints for general optimisation problems. An implementation of the LBFGSB algorithm version 3.0 would notably be very useful.
This feature was mentio…

Hello. Thanks for your project. I added it to my directory of Fortran codes https://github.com/Beliavsky/Fortran-code-on-GitHub.
In LBFGSB_wrapper.f90 and test.f90 you have

The conjugate gradient with constrained and LBFGSB needs to be tested properly.

Due to conflicts with blas embedded in Armadillo, aliases have been done in lbfgsb (Fortran code) to rename hand-coded blas primitives without any conflict (see Lbfgsb.3.0/CMakeLists.txt), i.e.

Hi,
I don't know to quick fix this, but `make mex` makes a mex file named (on my setup):
`lbfgsb_mex.mexa64`
I believe this should be just `lbfgsb.mexa64` because `make install` gives error:
