constrained variable metric method meaning in English
约束变度量法
Examples
- modified constrained variable metric method is adopted in this optimization, and the application of perturbation method in the re-analysis of the structure is studied
另外，还对结构重分析中摄动法的应用进行了讨论。 - modified constrained variable metric method is adopted in this optimization, and the application of perturbation method in the re-analysis of the structure is studied
另外，还对结构重分析中摄动法的应用进行了讨论。 - such methods are generally decreasing method, such as, feasible direction methods, constrained variable metric methods, etc . another class is sub-problems method, which approximates the optimal solution by solving a series of simple sub-problems, such as penalty function methods, trust region methods, and successive quadratic programming sub-problems, etc . the same property of two classes of methods is that they determine whether the next iterative point is " good " or " bad " by comparing the objective function value or merit function value at the current point and next iterative point
另一类叫做子问题算法，这种算法是通过一系列简单子问题的解来逼近原问题的最优解，如罚函数法、信赖域算法、逐步二次规划算法等。这两类算法的一个共同特点是，通过比较当前点和下一个迭代点的目标函数值或评价函数值来确定迭代点的“优”或“劣”，若迭代点比当前点“优”则该迭代点可以被接受，否则须继续搜索或调整子问题。
