How To Install liblpsolve55-dev on Ubuntu 18.04

In this tutorial we learn how to install liblpsolve55-dev on Ubuntu 18.04. liblpsolve55-dev is Solve (mixed integer) linear programming problems - library

Introduction

In this tutorial we learn how to install liblpsolve55-dev on Ubuntu 18.04.

What is liblpsolve55-dev

liblpsolve55-dev is:

The linear programming (LP) problem can be formulated as: Solve A.x >= V1, with V2.x maximal. A is a matrix, x is a vector of (nonnegative) variables, V1 is a vector called the right hand side, and V2 is a vector specifying the objective function.

An integer linear programming (ILP) problem is an LP with the constraint that all the variables are integers. In a mixed integer linear programming (MILP) problem, some of the variables are integer and others are real.

The program lp_solve solves LP, ILP, and MILP problems. It is slightly more general than suggested above, in that every row of A (specifying one constraint) can have its own (in)equality, <=, >= or =. The result specifies values for all variables.

lp_solve uses the ‘Simplex’ algorithm and sparse matrix methods for pure LP problems. If one or more of the variables is declared integer, the Simplex algorithm is iterated with a branch and bound algorithm, until the desired optimal solution is found. lp_solve can read MPS format input files.

This package contains the static library for developing programs using liblpsolve.
