Sizing optimization and material selection are also briefly commented. The prominent methods employed to generate optimal topological designs are homogenization, bubble insertion, nature analogy and ground structure. Similarly, the main algorithms used to perform shape optimization fall in one of the following categories: boundary variation, nature analogy and hybrid, such as, a machine learning system interfaced to the shape optimization environment. The practical use of such methods in the design of structures is discussed. Special consideration will be given to the nature analogy software algori
