ocplib-simplex
A library implementing a simplex algorithm, in a functional style, for solving systems of linear inequalities and optimizing linear objective functions
Overview
ocplib-simplex is a (fully) functional OCaml implementation of the
simplex algorithm for solving systems of linear inequalities. The
implementation is incremental and backtrackable. It is able to extract
unsat-cores for unsatisfiable problems. Versions > 0.1 also support
linear optimization
Dependencies
ocplib-simplex requires 4.01.0 or higher and ocamlfind.
You can use make opam-deps to install dependencies in the current switch.
Build and Install Instructions
The easiest way to install ocplib-simplex is to use OPAM:
$ opam install ocplib-simplex
If you want to install ocplib-simplex from sources, use the following instructions:
$ make opam-deps (if you are using OPAM and some deps are missing)
$ make
$ make install
to compile and install ocplib-simplex on your system. You can
uninstall the library with make uninstall.
Minimal Examples

TODO
-
the code is not (well) documented,
-
some parts of the code need factorization/simplification,
-
some invariants (check unsat-core, linear optimization) are missing.
