Designing a composite stiffened panel is a complicated process, and optimization techniques are proving helpful to engineers in designing a cost-effective, practical structure. Random search algorithms (cf. also  Random search methods), such as simulated annealing and genetic algorithms, are being used in the design of composite structures [3]. A benefit of these algorithms is that they can optimize functions that cannot be handled with traditional optimization techniques. In this article, a structural design problem for composite fuselage is described which involves solving a mixed integer global optimization problem. The objective function may be discontinuous, have many local optima, and the feasible region may be disconnected. The random search algorithm, improving hit and run [23], that is used to solve these composite structural optimization problems is also described in  Global optimization: Hit and run methods. Although a random search algorithmcan only provide a...
