Description

This library provide an algorithm to minimize and maximize functions of many variables on bounded or unbounded domains. This is a binding to L-BFGS-B, a library for Large-scale Bound-constrained Optimization.

OCaml bindings for L-BFGS

L-BFGS is an optimization algorithm in the family of quasi-Newton methods that approximates the Broyden–Fletcher–Goldfarb–Shanno (BFGS) algorithm using a limited amount of computer memory.

This library is a binding to Nocedal's implementation of L-BFGS-B which adds the possibility of setting bounds on the variables.

Install

The easiest way to install the library is to use opam:

opam install lbfgs

If you clone this repository, download Lbfgsb.3.0 and extract it in src/ (it should create src/Lbfgsb.3.0/). Then issue make and make install.

In case the right FORTRAN compiler for your platform is not automatically found, you can specify it explicitly by exporting the FORTRANC variable before invoking opam. For example

    export FORTRANC=/usr/bin/x86_64-w64-mingw32-gfortran.exe
opam install lbfgs

Documentation

If you cloned this repository, issue

dune build @doc

You can also consult the interface or online.

Build status

Results of building lbfgs with each compiler on check.ci.ocaml.org, run of against opam-repository 8a77e58. All results for this package.

Each result links to its build log. To keep crawlers from overloading the site, build logs require a GitHub sign-in (see ocurrent/opam-health-check). On your first log, GitHub asks you to “Authorize opam-health-check”, the OCurrent app that runs these checks; it sees only your public profile, not your repositories. The sign-in lasts 30 days.
