本算法描述了经典的和声搜索算法，以C语言实现，代码简单易懂，欢迎大家讨论交流，谢谢！！！和声搜索（Harmony Search, HS）算法是2001年Geem Z W 等人提出的一种新颖的智能优化算法。类似于遗传算法对生物进化的模仿、模拟退火算法对物理退火的模拟以及粒子群优化算法对鸟群的模仿等，和声算法模拟了音乐演奏的原理。

应用背景Massive multiuser MIMO (MISO): ◮ M ≫ K ≫ 1 (think 100 × 10 or 500 × 50) ◮ coherent, but simple, processing ◮ Potential to dramatically improve rate & reliability ◮ Potential to drastically scale down TX power ◮ Not only theory, at least one known testbed (64× ∼10) 关键技术 Massive MIMO Operation Not enough resources for pilots & CSI feedback, so operate in TDD. ◮ On the uplink, ◮ acquire CSI from uplink pilots and/or blindly from data ◮ detect symbols ◮ M ≫ K ⇒ linear processing (MRC, ZF, MMSE) nearly optimal ◮ On the downlink, ◮ use CSI obtained on the uplink ◮ make necessary adjustments based on reciprocity calibration ◮ apply multiuser MIMO precoding ◮ simple precoders desirable (and very good!): MRT, ZF, MMSE, ... ◮ MRC/MRT operation ◮ intracell interference will appear as

问题描述：设R={ r1, r2, ...., rn}是要进行排列的n个元素。其中元素r1,r2,......,rn可能相同。试设计一个算法，列出R的所有不同排列。 编程任务：给定n 以及待排列的n 个元素。计算出这n 个元素的所有不同排列。

实现算法可能的方法： 1. 未知节点利用邻居锚节点进行定位，没有邻居锚节点的未知节点无法定位。 2. 未知节点一旦被定位，就充当锚节点。这时没有邻居锚节点的未知节点在等到自己的邻居未知节点定位之后就可以进行定位。 3. 有邻居锚节点的未知节点只利用邻居锚节点进行定位，没有邻居锚节点的未知节点才利用已经定位了的邻居未知节点进行定位。 Centroid.m采用的第一种方法; Centroid_second.m采用的第二种方法; Centroid_third.m采用的第三种方法;
