Methods for structural optimization problems having discrete variables, or a mix of discrete and continuous variables, are treated. The original problem is replaced by a sequence of approximate, sub-problems of a more favourable structure. A method using a generalized Lagrangian function is presented. The primal minimization over the discrete variables is done using neighbourhood searches. The performance of the method is demonstrated on numerical examples. A branch and bound algorithm is used, for comparison, to obtain global minima for a convex structural optimization problem.
