Constrained Optimization
5
Most problems in structural optimization must be formulated as constrained minimization problems. In a typical structural design problem the objective function
is a fairly s

1. A beer can is supposed to hold at least specific amount of beer and meet other design
requirements. The can will be produced in billions, so it is desirable to minimize the cost
