读者写者问题
说明： 1、定义一个数据缓存buffer及用于实现同步互斥的信号量。
2、定义一个读者函数：
?当有写者在占用buffer时，读者应该等待，直到写者不再使用该buffer。
?当有其他读者在占用buffer时，读者可对buffer进行读取操作。
?当buffer中有数据时，则从其中读取一个数据，并显示然后退出。
?当buffer中没有数据时，应等待，直到buffer中有数据可读。
3、定义一个写者函数
?当有读者在占用buffer时，写者应该等待，直到所有的读者都退出为止。
?当有其他写者占用buffer时，该写者应该等待，直到占用buffer的写者退出为止。
?当buffer有空闲时，写者应该在buffer中写入一个数据并退出。
?当buffer满时，写者应该等待，直到buffer有空闲为止。
4、定义主函数，在其中可以任意创建读者与写者。
可根据用户输入创建读者或写者进程(线程)。(1. Define a data buffer and semaphores for synchronization and mutual exclusion.
2. Define a reader function:
When a writer is occupying the buffer, the reader should wait until the writer no longer uses the buffer.
When other readers occupy the buffer, they can read the buffer.
When there is data in the buffer, read a data from it, display and exit.
When there is no data in the buffer, wait until the data in the buffer is readable.
3. Define a writer function
When a reader is occupying the buffer, the writer should wait until all readers quit.
When other writers occupy the buffer, the writer should wait until the writer who occupies the buffer exits.)

说明： 模拟退火是 80 年代初发展起来的一种随机性组合优化方法。它模拟高温金属降温的热力学过程，并广泛应用于组合优化问题。基于模拟退火的粒子群优化算法是把模拟退火机制引入基本粒子群优化算法中，采用杂交粒子群优化算法中的杂交运算和带高斯变异的粒子群优化算法中的变异运算，以便进一步调整优化群体。(Simulated annealing is a stochastic combinatorial optimization method developed in the early 1980s. It simulates the thermodynamic process of high temperature metal cooling and is widely used in combinatorial optimization problems. The particle swarm optimization algorithm based on simulated annealing introduces the simulated annealing mechanism into the basic particle swarm optimization algorithm, and adopts the hybrid operation in hybrid particle swarm optimization algorithm and the mutation operation in particle swarm optimization algorithm with Gaussian mutation, so as to further adjust the optimization population.)
