First, handling three improved variants of differential evolution algorithms are dynamically matched with two constraint handling techniques through the constraint allocation mechanism. Each combination includes three variants with corresponding constraint handling technique?and these combinations are in the set. Second, the population is divided into three smaller subpopulations and one larger reward subpopulation. Then a combination with three constraint algorithms is randomly selected from the set, and the three constraint algorithms are run in three sub-populations respectively. According to the improvement of fitness value, the optimal constraint?algorithm is selected to run on the reward sub-population, which can share?information and close cooperation among populations. In order to verify the effectiveness of the proposed algorithm, 12 standard constraint optimization problems?and 10 engineering constraint optimization problems are tested. The experimental results show that ECMPDE is an effective algorithm for solving constraint optimization problems.展开更多

It is a traditional building with Chinese characteristics. Ancient Chinese pavilion is not only the classical architecture in Chinese landscape architecture, but also the symbolic literary image in the history of Chinese literature. The related research on ancient Chinese pavilion in the field of architecture is mainly carried out from the aspects of architectural modeling, structure construction, spatial mood, etc. and there is little research on the function evolution of ancient Chinese pavilion. Based on the perspective of literature and history, this paper studied the original function and evolution history of ancient pavilion in China from the perspectives of philology, history and literature.展开更多
