进程是程序在一个数据集合上运行的过程,进程是并发进行的,也即系统中的多个进程轮流的占用处理器运行。
我们把若干个进程都能进行访问和修改的那些变量称为公共变量。由于进程是并发执行的,所以,如果对进程访问公共变量不加限制,那么就会产生“与时间有关”的错误,即进程执行后,所得到的结果与访问公共变量的时间有关。为了防止这类错误,系统必须要用同步机构来控制进程对公共变量的访问。一般说,同步机构是由若干条语句――同步原语――所组成。本试验要求学生模拟PV操作同步机构的实现,模拟进程的并发执行,了解进程并发执行时同步机构的作用。
-process is a procedure in the data set to run the process, the process is conducted with the system that is the rotation process more than the occupier runs. We have a number of process can visit and revision of those variables as public variables. As the process is complicated by the implementation, so if the right to visit public process variables without restrictions, it will have a "Time" is wrong, the implementation process, the results obtained with the public to visit the variables of time. To prevent such mistakes, the system must be used to control synchronization process bodies for public variables visit. In general, synchronous bodies of a number of statements-- synchronization primitives-- composed. Th

K r u s k a l算法每次选择n
K r u s k a l算法每次选择n- 1条边,所使用的贪婪准则是:从剩下的
边中选择一条不会产生环路的具有最小耗费的边加入已选择的边的集合中。注意到所选
取的边若产生环路则不可能形成一棵生成树。K r u s k a l算法分e 步,其中e 是网络中
边的数目。按耗费递增的顺序来考虑这e 条边,每次考虑一条边。当考虑某条边时,若将其
加入到已选边的集合中会出现环路,则将其抛弃,否则,将它选入。-K ruskal algorithm for each choice of n-1 edges, the greed of the criteria used are: from the left edge select does not produce a loop with the smallest cost edge has been selected to join the edge of the collection. Taking note of the selected edges have a loop if it can not form a spanning tree. K ruskal algorithm sub-e-step, in which e is the number of network edge. According to the order of incremental cost to consider this e edges, each taking a side. When considering a certain edge when, if its added to a collection of selected edge loop will appear, will be its discarded, otherwise, it selected.
