In this paper, a method of establishing and analyzing the probability model of its mutation and crossoperation process for differential evolution (DE) algorithm is proposed; especially, the escape ability and further optimization ability of individuals trapped in the local optimal neighborhood are deduced in detail, and the characteristic curves of the influence of key parameters such as population size, scaling factor, and crossfactor on the search performance of the algorithm are obtained. It provides a theoretical reference for the application of the algorithm.

Abstract. Engineering education professional accreditation is a universal guarantee mechanism for the quality of engineering education. It is also the basic of international mutual recognition of the engineering education and engineer qualifications. This article explores the professional accreditation of electrical engineering and automation specialty in Shanghai DianJi University, with in-depth research in the training objectives, graduation requirements, curriculum system, practical aspects and evaluation system. Emphasizing on the development of technical ability and application capability, it aims to practically improve the education quality of application-oriented undergraduate education system of electrical engineering and automation specialty.
