Abstract In this paper, a two-level delimitative and combinatorial algorithm for a kind of (0,1,2) programming is proposed and applied to discrete optimization of structures. The algorithm generates all combinations in a certain order of magnitude of the function of the objective by using a two-level generating method and eliminates the majority of infeasible or nonoptimum combinations by using a two-level delimitative algorithm, so that computational efficiency is greater. Additionally, a (0,1,2) programming model of discrete structural optimization is established and the local optimum solution can be obtained by using this algorithm, thus it provides a method to judge whether or not the approximate optimum solution obtained by the heuristic algorithm is a local optimum solution.
