Evolutionary Structural Optimization (ESO) is a simple and robust numerical method for optimization problems applicable to various types of structures. The basic idea of ESO is that by slowly removing inefficient material, the residual structure evolves towards an optimum. The significance of ESO is its simplicity and generality. It can be used for a whole range of structures including truss, frame, plate /shell and 3D continuous bodies. The optimization constraints can be stress, stiffness, displacement, frequency or buckling load and dynamic response. This paper introduces the theories, procedures and latest techniques of ESO. A number of examples of engineering design problems have been presented to demonstrate the capability and effectiveness of ESO.
