## The graphical method

The graphical method is a technique for solving linear programming problems that is primarily used for cases with two variables. Although it is not very practical for a large number of variables, it is very useful for interpreting and analyzing the results and sensitivity of the problem. However, in cases where a greater number of variables is required, it is…

## Simplex Method

Simplex method is a solving problem analytic method of linear programming, able to resolve complex models than the resolved through graphic method. Simplex method is an iterative method that improves the solution on each step. The mathematical reason of this improvement is that the method consists in walking through a neighbor vertex in such a way that raises or decreases…

## Linear programming

Linear Programming corresponds to an algorithm trough which real situations can be solved in which the goal is to identify and resolve difficulties to rise productivity about resources (mainly limited and expensive resources), raising like this the benefits. The main goal of Linear Programming is to optimize (minimize or maximize) linear functions in many real variables with linear constraints (linear…
