应用于液压集成块优化的一种混合遗传-退火算法 总被引:1,自引:0,他引:1
This paper establishes a mathematical model of multi-objective optimization with behavior constraints in solid space based on the problem of optimal design of hydraulic manifold blocks (HMB). Due to the limitation of its local search ability of genetic algorithm (GA) in solving a massive combinatorial optimization problem, simulated annealing (SA) is combined, the multi-parameter concatenated coding is adopted, and the memory function is added. Thus a hybrid genetic-simulated annealing with memory function is formed. Examples show that the modified algorithm can improve the local search ability in the solution space, and the solution quality. 相似文献

师:同学们,我们以前学过一些寓言,你还记得这些寓言的题目吗?生:记得。如《自相矛盾》《掩耳盗铃》等。师:说得很好。请想一想:寓言是什么意思?则是什么词?生:寓言就是假托一个故事,告诉我们一个深刻的道理的小文章。生:寓是寄托、假托的意思。生:则是表示量的词。师:同学们答得很好。这节课我请同学们先看一幅图片。(出示投影:一个汗流满面的人正在一棵一棵地拔禾苗。)谁来说说图片的内容?生:一个人正在干活。生:一个人往高拔禾苗。师:说得很好。今天我们就来学习寓言《揠苗助长》。(板书课题)〔评:投影放图片,有… 相似文献
