资源描述kmenas算法首先选择K个初始质心，其中K是用户指定的参数，即所期望的簇的个数。这样做的前提是我们已经知道数据集中包含多少个簇，但很多情况下，我们并不知道数据的分布情况，实际上聚类就是我们发现数据分布的一种手段

DBSCAN算法的Java实现  DBSCAN是一种基于密度的聚类算法，它的基本原理就是给定两个参数，ξ和minp，其中 ξ可以理解为半径，算法将在这个半径内查找样本，minp是一个以ξ为半径查找到的样本个数n的限制条件，只要n>=minp，查找到的样本点就是核心样本点

This is the project of my course in the USA: Customers arrive at a service station (with a single server) according to the Poisson process with a mean arrival rate of lambda = 0.3 (customers/min). Each customer waits in queue (if present), proceeds to receive service upon his/her turn, and departs the system when the service is completed. The service time is uniformly distributed between 2.5 and 4.5 minutes. On each day, the service station is open for two hours. Any customers in queue at the end of work hours are served before closing the service station for the day. Use simulation (do 100 simulation runs) to determine
