This movie gives a brief overview of the strategy for choosing your row operations no matter what it is you’re trying to do. Whether it’s to solve a system of equations or to find an inverse....

I will now talk about the parametric cost vector. So, I told you that this is nothing but the dual of the parametric right hand side problem, but we will handle it independently; so, the problem would...

Before I continue with the duality theory, I just thought I will check, I think I wrote the, so this in the last lecture when we were computing the solutions for the bounded variable linear problem....

In this video i'm going to summarize the ideas for solving systems of linear inequalities. We actually have worked through a few examples of solving linear inequalities using a method which is...

Let me revise it assignment 7 just for a moment, I discussed it in the last lecture, and in problem 3 part 6, I had asked you to consider the case when the capacity is reduced, so arc 2, 5 had a flow...

So, let me now defined another entity that we need to consider various kinds of structures that a polyhedron can have. Now, here let me defined a direction of..., and I am doing it for a polyhedron...

So here is our GeoGebra solution to example 1. This purple region represents all of the possible solutions to the problem and we have found the intersection points A, E, D and O and tested our...

In this mathcast we continue to show how to use GeoGebra to do Linear Programming. Our constraints here are x greater than or equal to 0 and y greater than or equal to 0, 6x plus 4 greater than or...
