To define a constraint, you first compute the value of interest using the decision variables. Then you place an appropriate limit (<=, = or >=) on this computed value. The following examples illustrate a variety of types of constraints that commonly occur in optimization problems.
How do you calculate 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.
How do you solve constrained problems?
The commonly used mathematical technique of constrained optimizations involves the use of Lagrange multiplier and Lagrange function to solve these problems followed by checking the second order conditions using the Bordered Hessian.
