In general the Lagrangian is the sum of the original objective function and a term that involves the functional constraint and a 'Lagrange multiplier' λ
The Lagrangian formulation is of a very general nature and makes use of generalized coordinates and velocities which are independent of the coordinate system. Constraints: The motion of a free particle is described by three independent coordinatesx,y,z in Cartesian system or r,θ, ɸ in polar coordinates.
What is the formula for constrained optimization?
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. We then evaluate the function f at each point (x,y) that results from a solution to the system in order to find the optimum values of f subject to the constraint.
