Introduction

------------

What is lp_solve and what is it not?

The simple answer is, lp_solve is a Mixed Integer Linear Programming (MILP) solver.



It is a free (see LGPL for the GNU lesser general public license) linear (integer) programming solver

based on the revised simplex method and the Branch-and-bound method for the integers.

It contains full source, examples and manuals.

lp_solve solves pure linear, (mixed) integer/binary, semi-continuous and

special ordered sets (SOS) models.



See the reference guide for more information.





lp_solve 5.5

Why a jump from version numbers 5.1 to 5.5 ?

This is done to indicate that this is more than just another update.

The solver engine was revised and optimised in such a way that performance has improved considerably.

Numerical stability is also better resulting in more models that can be solved.

The LUSOL bfp is now also the default. In the past, the etaPFI bfp package was the default,

but for larger models this leads faster to nume
