Description: 分治法解决最近对问题
画一条垂直线x=c，把这些给定点分为两个包含n/2个点的子集S1和S2，使得n/2个点位于直线的左侧或直线上，另外n/2个点位于直线的右侧或直线上；遵循分治法的思想，递归地求出左子集S1和右子集S2中的最近对，分别为d1与d2；之后d=min{d1,d2}。合并过程：在以垂线x=c为对称轴，2d为宽度的区域内求最近两个点的距离，记为d3；求D=min{d,d3}；
-Sub-rule method to resolve the issue of the recent draw a vertical line x = c, a given point of these two contains n/2 points in a subset of S1 and S2, making n/2 points located on the left side of a straight line or straight line the other n/2 points located on the right side of a straight line or straight line follow the idea of sub-rule method, recursive subset to derive the left and right S1 subset S2 of the recent right, respectively, d1 and d2 after d = min (d1, d2). The merger process: in the vertical line x = c as the axis of symmetry, 2d is the width of the region for the last two points the distance is recorded as d3 for D = min (d, d3)

Description: Titest and orthotest are programs for calculating how close to
transversely isotropic or orthorhombic a set of 21 elastic constants are.
General anisotropy requires 21 velocity parameters to describe.
Orthorhombic media have 3 perpendicular planes of symmetry, and require 9.
Transversely isotropic ("TI") has an axis of rotational symmetry and
requires only 5. There is no proprietary information in these programs
they merely implement equations described in a paper by Patrick Rasolofosaon
of IFP. (Note there are typos in some equations listed in that paper.)
Those equations define a "distance" measure between two sets of 21 elastic
constants. The only "tricky" coding in these programs is how I do the
search over all possible orientations of the anisotropic symmetry axes.-Programs for finding the nearest VTI and Orthorhombic medium to an arbitrary set of 21 stiffness constants

Description: 正方形薄板四周受均匀载荷的作用，该结构在边界上受正向分布压力 ，同时在沿对角线y轴上受一对集中压力，载荷为2KN。
由于连续平板的对称性，只需要取其在第一象限的四分之一部分参加分析，然后人为作出一些辅助线将平板“分割”成若干部分，再为每个部分选择分析单元。采用将此模型化分为4个全等的直角三角型单元。利用其对称性，四分之一部分的边界约束，载荷可等效如图所示。-Square plate under uniform load around the role of the structure of the distribution on the boundary by positive pressure, while the y axis along the diagonal by a Pair of pressure, load the 2KN. The symmetry of the continuous plate, whichever is only one quarter in the first quadrant of some of the participants, and then make some people will flat guides " split" into several parts, and then select the unit of analysis for each section. Using this model is divided into four congruent right-angle triangle unit. Use of its symmetry, a quarter part of the boundary constraints, loads can be equivalent to as shown.
