A nongradient direct search procedure is presented to treat general structural optimization problems in which the independent design variables are discrete in nature. The procedure combines the complex method of M. J. Box with the pattern search of R. Hooke and T. A. Jeeves. Examples of design considered include a framed structure and a tied cantilever beam under static loads, and a two-layered slab under dynamic loads.
