＜正＞A class of hybrid niching evolutionary algorithms（HNE） using clustering crowding and parallel local search is proposed By analyzing topology of fitness landscape and extending the space for searching similar individual,HNE determine the locality of search space more accurately,thus decreasing the replacement errors of crowding and suppressing genetic drift of the *** integration of deterministic and probabilistic crowding increases the capacity of both parallel local hill-climbing and maintaining multiple subpopulations. Parallel local search based on simplex method over disjoint subpopulations greatly speed up the convergence of the population towards various optima *** coded representation and Gaussian mutation improve the precision of the solutions *** experimental results optimizing various multimodal functions show that,the performances of HNE such as the number of effective peaks generated and maintained,average peak ratio,global optimum ratio and CPU time consumed are uniformly superior to those of genetic algorithms using sharing,deterministic crowding method.

The 7th International Conference on Computer-Aided Industrial Design and Conceptual Design (CAID&CD’2006)

作者： YAN Tai-shan 1 2 CUI Du-wu 1 (1. Institute of Automation Science Xi’an University of Technology Xi’an Shaanxi 710048) (2.Department of Computer Science hunan Institute of Technology Yueyang hunan 414000)

The technique of automated visual inspection is a new development in computer inspection. It has many advantages such as no touching with inspected objects, high speed, high efficiency and good flexibility, etc.. So it has extensive applied foreground in the modern automatic inspection of product quality. This paper introduces the general structure of the computer vision inspection system, expounds the realization method of an on-line crack inspection system of glass bottles, which combines with neural network principle. The system’s ability to learn itself and adapt itself is very powerful, it has realized a quick and exact inspection of the on-line glass bottles’ crack successfully.
