Two Variables: Graphical Solution For cases like the one we have here, where there are just two decision variables, there is a quick and easy solution method. This method involves graphical ...

In this paper a unified treatment of algorithms is described for linear programming methods based on the central path. This path is a curve along which the cost decreases, and that stays always far ...

Moreover, a new, ratio-test-free pivoting rule is proposed, significantly reducing computational cost at each iteration. Our numerical experiments show that the method is very promising, at least for ...
