约束

与 约束 相关的网络例句 [注:此内容来源于网络,仅供参考]

This is considered as a constrained optimization problem, and CUA employs L-BFGS-B, a limited memory quasi-Newton algorithm, to solve it.

CUA将展平或修正过程考虑为一个约束优化问题,然后采用适用于约束问题的有限内存拟牛顿法L-BFGS-B来求解。

These experimental results demonstrate that CUA adapts to both constrained and unconstrained problems, and has the virtues of occupying little memory, computing quickly and accurately, supplies the designers with sufficient convenience during the design stage.

这些例子验证了CUA既可以求解约束问题,也可以求解无约束问题,并且具有占用内存小、计算速度较快和精度较高的优点,可以为设计者在产品设计阶段提供便利。

In consideration of the cyclic symmetry of displacement constraints of group blades, a skew boundary condition and a skew coordinate system are introduced to deal with the constraint condition of group blades or integral blades.

该模型考虑到成组叶片位移约束的周期对称性,引入了料边界条件和斜坐标系统来处理成组或整圈叶片的约束条件,从而可以准确地计算出三维复杂形状叶片组在动、静状态下的固有频率和振型。

Finally, the change of joint angular velocity of the supporting leg is deduced based on the Lagrange dynamic equation when a foot of the robot collides with the ground.3, Dynamic stability conditions of the robot in stance phase and flight phase are derived based on the D\'Alembert principle.

这种动力学方程由微分方程和代数约束方程组成,其优点是通过稍微修改约束方程和雅克比矩阵,就可以方便地建立各自动力学方程,建模速度快、精度高。

Many of the elements below each constraint element PRO_E_DTMPLN_CONSTRAINT are used only for certain constraint types, so any given datum plane may contain fewer elements than are shown in the tree.

许多下面每个约束元素 PRO_E_DTMPLN_CONSTRAINT 只使用确定的约束类型,所以任何给定的基准平面可能包含比树里看到的少些的元素。

The first level and the lower level both have their objective functions and constraint conditions, the objective function and constraint conditions of the first level not only have relations with the upper decision variable, but also depends on the optimal value of the lower level.

上层和下层各有目标函数和约束条件,上层问题的目标函数和约束条件,不仅与上层决策变量有关,而且还依赖于下层问题的最优解或最优值。

When you remove a deferrable constraint, its index remains.

当用户移除一个可延迟的约束时,此约束使用的索引仍将被保留。

Under these constraints,the value and change of every constraint parameter would cause influences on the strategy choices of supplier and demander and the quality of final product.

在这些约束下,各个约束参数的大小以及变化对供求双方的策略选择以及最终产品的质量都会构成影响。

It is also presented that DP model can be used to support model derivation.

首次提出用约束实现对DP模型的描述,建立了相应的约束描述机制。

Comparing with the traditional deterministic optimization results,reliability optimization results meet the established design objectives better,and increase the reliabilities of the design restraints significantly.

与传统的确定性优化结果相比较,可靠性优化结果不仅较好地满足了乘员约束系统的设计目标,而且大幅度地提高了系统设计约束的可靠性。
