I use the method of the Lagrange Multipliers by setting: The only things that are unknown in the equations are the Lagrange multipliers, the lambdas. Everything else depends on the empirical data available, and are thus just numbers. Given a set of values for the lambdas, you can calculate the G(j,r) and the Jacobian J(j,i,r,s). In turn, if you know the residuals and the Jacobian, you can use Newton ...My university's version of calc 3 just hit upon constrained optimization using Lagrange Multipliers. The concept was simple enough to grasp: the gradient of the function and the gradient of the constraint are proportional and related by a constant multiple. Set up a system of equations, solve, then you're golden.The method of Lagrange multipliers. The general technique for optimizing a function f = f(x, y) subject to a constraint g(x, y) = c is to solve the system ∇f = λ∇g and g(x, y) = c for x, y, and λ.
