无约束问题 meaning in Chinese
unconstrained problem
Examples
- ( 4 ) penalty function method is used to import the constrains into the objective function
( 4 )本文利用“惩罚函数法”将约束问题转变为无约束问题。 - We make some improvements on it . as an efficient method to solve the optimization problems in svms , newton - pcg algorithmhas been introduced
在算法方面，本文在将支持向量机中的最优化问题转化为无约束问题的前提下，研究了newton - pcg算法。 - Newton - pcg algorithm is very efficient for solving the unconstrained optimization problems . we considered an integer one - dimensional optimization problem appeared in newton - pcg method . the efficiency of newton - pcg algorithm is depended on the optimal value of this problem
Newton - pcg算法是解决无约束问题的有效方法，在该算法中需要求解一个一维整数最优化问题，并且算法的效率也依赖于它的最优值。 - However , some of them are restrictive . for some of these methods , the convergence is not known in this paper , based on a modified bfgs update formula proposed by li and fukushima , we propose a modified bfgs method for solving equality constrained optimization
本文在li - fukushima提出的求解无约束问题的修正bfgs公式的基础上，对求解等式约束问题的sqp算法，提出一个保证qp子问题的目标函数的hessian阵的正定性的修正方案。 - Optimal design with three variables is then done to the elbow - bar mechanism of the mp1040b moulding machine by utilizing the method of punishing function for constraint problems and variational scale for unconstraint problems . the optimal target function is the maxium of gradient in one work travel for the moulding plank of the elbow - bar mechanism . the result shows that the maximal gradient of moulding plank in one motion period declines by 25 . 7 after optimization , and the angular acceleration of the bottom moulding plank decreases greatly
动力学分析中，各构件的质量和转动惯量是通过pro / engineer软件，先建立各个构件几何模型而求得；然后，利用解决约束问题的罚函数法和处理无约束问题的变尺度法对mp1040b型模切机肘杆机构进行三个设计变量的优化设计，优化目标函数为肘杆机构的下模切板在一个工作行程中达到的最大倾斜程度；通过优化设计，模切机肘杆机构的下模切板在一个工作行程中的最大倾斜程度降低了25 . 7 ，其角加速度明显减小，提高了模切机动力学性能。
