【Abstract】 This paper theoretically discusses the possibility of combining genetic algorithm (GA) with sequence unconstrained minimization technology. The study shows this combining method is the best fit for solving complex nonlinear constraint optimum problems. As a example, it successfully realizes a calculation of the probability & reliability optimum design for a two-grade general helical cylindrical gear reducer. Compared with the traditional optimum methods, it can obtain an ideal global optimum result and improves GA’s limitation.更多还原
