lbfgsb: The FORTRAN 77 code from Nocedal (et al) that implements L-BFGS-B, in its original form. I have included only the files from their distribution that are necessary to build and run L-BFGS-B for this project (although I have retained their README). For their full distribution, which includes papers on the algorithms and code, sample programs, sample outputs, etc., visit http://users.eecs.northwestern.edu/~nocedal/lbfgsb.html.

Note on L-BFGS-B License

The L-BFGS-B distribution comes with a blank BSD 3-Clause License template. I filled in the template based on the stated authors and year on the web page above. Hopefully it will match their intentions but the license is not original to their code.
prototype: Code for experimenting with foreign function interfaces between Fortran, C, and Go. Use it as a seed for your own experiments!

Files

Files are either part of the L-BFGS-B library or the Go package.

lbfgsb.f03: Fortran 2003 interface to L-BFGS-B FORTRAN 77 code. This and the code in lbfgsb/ are the core of the library.
lbfgsb_c.*: C declarations and Fortran 2003 code for library C API.
*.go: L-BFGS-B Go package.
lbfgsb_go_interface.*: C files for Go package.
