Structural optimization

"Structural optimization may be defined in various ways. One definition could be the design and construction of a quality structure at the lowest cost. This definition often turns out to be inappropriate due to both the difficulty of giving a precise definition to cost and the dependence of the cost function on highly variable factors.
