Key Concepts

Constrained Optimization

Constrained optimization is the process of optimizing (maximizing or minimizing) an objective function subject to constraints. It deals with situations where the solution must comply with one or more conditions, and techniques like the method of Lagrange multipliers are used to account for these restrictions while finding the optimal solution.

Gradient

The gradient of a function is a vector that consists of all its partial derivatives, indicating the direction of the steepest increase of the function. In optimization problems, especially when using Lagrange multipliers, the relation between the gradients of the objective function and the constraints is fundamental since their alignment at an optimal solution is what the method exploits.

Lagrange Multipliers

Lagrange multipliers are a strategy for finding the local maximum and minimum values of a function subject to equality constraints. The main idea is that at the extrema, the gradient of the function is parallel to the gradient of the constraint, which allows one to set up a system of equations to solve for the critical points.
