다국어 초록 (Multilingual Abstract)

With the development of quantum computer, the quantum-inspired search method applying the features of quantum mechanics, i.e. indetermination, superposition, entanglement, etc, and its application to engineering-problems have emerged as one of the most interesting research topics. Unlike the study of the quantum computer, the quantum-inspired search algorithms have been developed based on the application of the existed meta-heuristic algorithm and the information superimposed quantum-bit approached via through quantum gate. In this process, it appears that the balance between the two features of exploration and exploitation, and continually accumulates evolutionary information. Thus, this study is to propose a quantum-inspired harmony search algorithm and to solve the structural optimization problem by the algorithm. For the optimization, we suggest the mathematical modeling of the truss which is possible to minimum weight design. In its model, the cost function is minimum weight and constraint function consists of the stress. To trace the accumulative and convergence process of evolutionary information, 3-bar and 10-bar truss are chosen as the numerical examples, and their results are analyzed. The optimized design result in the numerical examples shows it has better result in minimum weight design, compared to those of the other search methods. It is also observed that more accurate optional values can be acquired as the result by accumulating evolutionary information.
