用matlab编写的求解武器目标分配的遗传算法程序(Using matlab to solve the distribution of weapons and target the genetic algorithm)

设计一个动态分区式存贮区管理程序，要求支持不同的放置策略，如首次、最佳、最坏。对于内存中的每一块分区，都需要一个分区描述器来描述其状态，且分区描述器之间按链表连接。这一步需要两个主存队列，一个存储自由分区，另一个存储已占用的分区。对于每一个任务，需要有申请和释放的函数，而根据放置策略的不同函数的实现也有所不同。考虑到内存会被不断读写，还需要程序能循环处理用户的请求。在内存分配的过程中，要注意到分区描述器也要占用一个单位的空间，已分配区也要尽量占用高地址处的空间。回收内存时还要想到需要合并的情况。每次申请或释放内存后即输出当前的内存状态。

将国密算法SM3, SM4 ECB的C代码打包成dll库。 然后在C#中进行调用。 有输入输出接口，测试结果正确。 包含所有源代码，可在此基础上进一步开发(The C code of the Chinese national algorithm SM3, SM4 ECB is packaged into a dll library and then called in C# with input and output interfaces. The test result is correct. Contains all source code and can be further developed on this basis)

在linux环境下编写一个控制台应用程序，程序中有一个共享的整型变量shared_var，初始值为0；创建一个线程并使其立即与主线程并发执行。新创建的线程与主线程均不断地循环，并输出shared_var 的值。主线程在循环中不断地对shared_var 进行加1操作，即每次循环shared_var 被加1；而新创建的线程则不断地对shared_var 进行减1 操作，即每次循环shared_var 被减1。观察程序运行的结果，并对你看到的现象进行解释。(Written in the linux environment a console application, the program has a shared integer variable shared_var, the initial value of 0 create A thread and make it run concurrently with the main thread immediately. The newly created thread and main thread are constantly circulating, and the output shared_var Value. The main thread in a loop constantly on shared_var are incremented, that is plus 1 for each cycle shared_var and the new line created Process is constantly on the shared_var decremented, that is, each cycle shared_var is decreased by 1. Observe the results of running the program, and you To explain the phenomenon seen.)
