In mathematical optimization, the method of Lagrange multipliers is a strategy for finding the local maxima and minima of a function subject to equation constraints (i.e., subject to the condition that one or more equations have to be satisfied exactly by the chosen values of the variables).
In a previous post, we introduced the method of Lagrange multipliers to find local minima or local maxima of a function with equality constraints.
The same method can be applied to those with inequality constraints as well.16 mar. 2022
Inactive Constraint An inequality constraint gi(x) ≤ 0 is said to be inactive at a design point x(k) if it has negative value at that point, i.e., gi(x(k)) ≤ 0.
Violated Constraint An inequality constraint gi(x) ≤ 0 is said to be violated at a design point x(k) if it has positive value there, i.e., gi(x(k)) ≠ 0.
