In linear programming, constraints define the range and objective function defines the amount to be optimised. We can confirm that the point r=5.4192608391249 is an absolute minimum for A by applying the First Derivative Test. The equation is a combination of variables, whereas hidden constraints are individual inequalities for each variable. However, there is a barn on one side of the field (thus, fencing is not required on one side of the rectangular field). Intuitively, we know that to minimize surface area, we should build a can that holds 1 liter of liquid. It can be any higher degree polynomial or any complex function like exponential etc. An example of a problem that is well-suited for CP is employee scheduling.
