【Abstract】 There are many problems of two three dimension objects with complicated profile in the process of B I W assembly, which cause many assembly mating problem. In order to solve this kind of problem,a novel algorithm based on genetic algorithm for determining the optimal fitting of one three dimension curve is discussed and its convergent speed is improved. The solution to constrained optimization by applying genetic algorithm is described in detail. Some improved GA methods used in the constrained optimization is presented.更多还原
