Optimization method of truss structure size and shape based on harmonic search genetic algorithm
Published 2025-03-01“…In order to improve the traditional design concept and the lack of optimization of genetic algorithm, and promote the development and innovation of the shape optimization of truss structure, according to the basic principles of harmony search algorithm and genetic algorithm, a new hybrid genetic algorithm-harmony search genetic algorithm was proposed (the mixing of genetic algorithm and harmony search algorithm is to embed the harmony search operator after the operation of the genetic algorithm), and at the same time the cross-variation in the genetic algorithm was adaptively improved in three situations, and elitism and other improvement measures were introduced. …”

Structure of Interregional Economic Interactions as a Factor in the Formation of System Effects in National Economies
Published 2025-06-01“…At the same time, the set of countries united by the criterion of the presence of functional hierarchies in them is not homogeneous in terms of the role of different types of effects in the formation of hierarchical structures. The work explains the variation in the values of spatial multipliers depending on what variant of the structure of interregional economic interactions characterizes the national economic space, and within the framework of this explanation the consequences of illusions of a simple solution to the complex problems of spatial organization of the economy of a ?…”
