## 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

Solving a system of linear inequalities: see the file `tests/standalone_minimal.ml`

Linear optimization: see the file `tests/standalone_minimal_maximization.ml`

### Contributing

Don't hesitate to report encountered bugs on this Git repo's issues tracker.

### TODO

the code is not (well) documented,

some parts of the code need factorization/simplification,

some invariants (check unsat-core, linear optimization) are missing.
