罚因子 meaning in Chinese
penalty factor
Examples
- Solving of variational inequality with alternate direction method including extensive variable penalty factor
用带广义可变罚因子的交替方向法求解变分不等式 - A constitutive model of 3d contact with friction is established with the use of penalty parameter and an incremental statement of problem is carried out
借助罚因子建立了三维摩擦接触边界的本构模型，给出了三维摩擦接触问题的增量描述，推导了接触问题的互补虚功方程。 - With the method , all integrals can be easily fulfilled on regular sub - domain boundaries , and to impose the essential boundary conditions , a penalty parameter can be used so that a positive definite and symmetric stiffness matrix may be obtained
计算中，积分都在规则形状边界子域上完成，因而容易实现；通过罚因子添加本质边界条件，从而使得到的刚度矩阵是正定对称矩阵。 - Secondly , the penalty coefficient may converge to infinity in many situations when the iterative point is closely near the bound of feasible set , while the parameters are bounded if the solution set of constrained optimization is nonempty , which is available for numerical computation
另外在很多情况下，罚函数法中的罚因子当迭代点接近可行域边界时趋于无穷大，而参数控制算法中，只要约束优化问题有最优解，则参数是有界的，这对数值计算是有利的。 - The parameter control methods are very similar to penalty function methods , both of them are to solve constrained optimization problems by solving a series of sub - unconstrained optimization problems . but parameter control methods are different from penalty function methods . firstly , the penalty coefficient of penalty function methods are preassigned , while the parameters of parameter control methodsare generated automatically according to some rule prescribed
参数控制算法虽然与罚函数法非常类似，都是通过求解一系列无约束极小化问题来逼近约束优化问题的最优解，但罚函数法中的罚因子是预先设定的，而参数控制算法中的参数是自动产生的。
