【Abstract】 An optimization method of variant step length based on precision and two new concepts “variant step length based on precision” and “one dimensional search based on the sorting” are presented.They make the optimum design closely combined with precision of every design variable.In addition,the authors propose that for a multi peaked one dimensional search problem its optimum solution can be obtained by ordinary optimization methods only when the convexity or concavity of the objective function matches the step length determining the one dimensional search region and the method of finding the optimum step length factor.更多还原
