Example 4 Consider the linear program: Bug fixed - The karmarkar function required the initial guess x0.

Here, the initial guess x0 is given. The features of the quapro module are: Linear Programming Linlro in Scilab last edited In the case where the variable x is unrestricted, we can write it as the difference of two positive variables: These algorithms are now directly provided by Scilab 5. Management of inequality constraints.

Linear Programming Examples in Scilab

Linear Programming Examples in Scilab The goal of this page is to gather various examples of linear programming in Scilab. This is why the resolution required two steps: Acknowledgments We thank Reinaldo Golmia Dante for providing the initial material for this document.

Computation of the exitflag. The number of iterations can be put as an output argument.

We introduce slack variables and get: Assume that we must solve the linear program: Another version of the same idea was presented in "A modification of karmarkar's linear programming algorithm" by Vanderbei et al. It is able to solve the linear program either in standard form: This algorithm discovered by Dikin inand then re-discovered by Barnes and Vanderbei et al in Changes in Scilab 5. The detailed changes are the following: There are three main cases.

Facing problem with "linpro" function of scilab

There are also bugs which have been fixed: From there, there are two cases, depending on the constraint on x: Interior point methods", Example The quapro module http: If the feasibility problem has no solution, then the original problem has no solution. Bug fixed - The karmarkar function printed oinpro messages.

The linpro function can solve linear programs in general form: This method is used by the karmarkar function since Scilab 5. Bug fixed - The karmarkar help page did not document the eps, gamma, and crit arguments. In this page, we will focus of the linpro function.

Then we solve the modified linear program. This example is the example 1. This leads to the linear program: The simplex method", Example Freedman, Algorithmica, Volume 1, Numbers, Barnes, Mathematical Programming, Volume 36, Number 2, ,
