## This is clearly not the case for any f= f(y;z). Hence, in this case, the Lagrange equations will fail, for instance, for f(x;y;z) = y. Assuming that the conditions of the Lagrange method are satis ed, suppose the local extremiser xhas been found, with the corresponding Lagrange multiplier . Then the latter can be interpreted as the shadow price

So the gradient vectors are parallel; that is, ∇f (x 0, y 0) = λ ∇g(x 0, y 0) for some scalar λ. This kind of argument also applies to the problem of finding the extreme values of f (x, y, z) subject to the constraint g(x, y, z) = k. known as the Lagrange Multiplier method. This method involves adding an extra variable to the problem called the lagrange multiplier, or λ. We then set up the problem as follows: 1. Multiply speeds by individual link speed multiplier Multiply capacities by individual link capacity multiplier. 8. 405 NB ML LA GRANGE. D and ﬁnd all extreme values. It is in this second step that we will use Lagrange multipliers.
