Introduction to Design Optimization - UVic.ca
www.engr.uvic.ca• Frequently, the design objective, or cost function cannot be expressed in the form of simple algebra. Computer programs have to be used to carryout the evaluation on the design objective or costs. For a given design variable, α, the value of the objective function, f(α), can only be obtained using a numerical routine.
