DESIGN OF STEEL STRUCTURES

《优化设计》这门课程中的优化方法的作业，代码思路清晰，运行后没问题。包括，powell法，共轭梯度法，牛顿法，阻尼牛顿法，单纯形法，变尺度法等等。梯度法在第二个目标函数优化时并没有达到理想的点，陷入局部最优，阻尼牛顿法在第二个目标 函数处也精度不高。 用共轭梯度法配合牛顿法一维搜索来第二个目标函数时出现了 NaN 的情况， 是因为牛顿法的代码中运行时出现了分母为0的情况， 但是我在分母加了一个很小的数0.000001之后还会出 现，而已开始用变尺度法和牛顿法优化的时候也出现的 NaN 问题就消失了

对源代码做了少量修改，源代码来源忘记了; 代码为ViBe背景检测算法，也可用来做前景检测或者运动检测相关的内容； 检测效果较好，可通过参数进行调节 样本更新率等。

做网格的好程序，PARAMESH is a package of Fortran 90 subroutines designed to provide an application developer with an easy route to extend an existing serial code which uses a logically cartesian structured mesh into a parallel code with adaptive mesh refinement(AMR). -Do a good grid procedures, PARAMESH is a package of Fortran 90 subroutines designed to provide an application developer with an easy route to extend an existing serial code which uses a logically cartesian structured mesh into a parallel code with adaptive mesh refinement (AMR).

这是一篇讲述聚类在文本挖掘中的应用的博士论文,个人认为讲述的还是比较细的.-This is a talk about clustering in text mining applications in the doctoral thesis, individuals think about the still relatively small.

用遗传算法求y=x*sin(10*pi*x)+2的最大值  -1=

您可以添加整数列表并在屏幕上打印。如果你想的话，你可以先添加，后添加，再反向添加。

这个代码可以直接运行，能够在较快的时间内完成a e mod m 的运算，并且拥有图形化的界面。使用起来十分方便。

4个关于二维积分函数的C程序，以及示例，来自《C语言数值常用程序》，所以程序均经过本人测试可以正常使用！-four two-dimensional integral function of the C procedures, as well as examples from the "C language commonly used numerical procedures," and so I have to undergo testing can be used normally.

行编辑算法：可将输错的单个字符删除，也可将又错误的一行字符删除。操作简便。用栈来实现上述功能。-line editor algorithm : can be wrong deletion of a single character, and it can also wrong to delete his characters. Easy to operate. Stack used to achieve the above functions.
