More Lagrange Multipliers Notice that, at the solution, the contours of f are tangent to the constraint surface. The simplest version of the Lagrange Multiplier theorem says that this will always be the case for equality constraints: at the constrained optimum, if it exists, “ f will be a multiple of “g.

6 days ago · The Lagrange multiplier, λ, measures the increase in the objective function ( f ( x, y) that is obtained through a marginal relaxation in the constraint (an increase in k ). For this reason, the Lagrange multiplier is often termed a shadow price. For example, if f ( x, y) is a utility function, which is maximized subject to the constraint that ...
