Design Theory and Methods using CAD/CAE

5.3. Solution Techniques

As discussed earlier, the brute-force approach (e.g., the generative method) requires too many function evaluations; as a result, it is impractical for solving general engineering problems. Numerous solution techniques have been proposed, with consideration of minimizing the number of function evaluations, among other factors. Because a primary goal of multiobjective optimization is to model a designer's preferences (ordering or relative importance of objectives and goals), methods are categorized depending on how the designer articulates these preferences: methods with a priori articulation of preferences, methods with a posteriori articulation of preferences, and methods with no articulation of preferences.
