说明：  哲学家进餐问题是荷兰学者Dijkstra 提出的经典问题之一,它是一个信号量机制问题的应用,在操作系统文化史上具有非常重要的地位。对该问题的剖析有助于学生深刻地理解计算机系统中的资源共享、进程同步、死锁等问题,并能熟练地应用信号量来解决生活中的控制流程,即将生活中的控制流程用形式化的方式表达出来。
(Dining philosophers problem is that the Dutch scholars Dijkstra classic one of the issues raised, it is a semaphore mechanism for the application of cultural history in the operating system has a very important position. Analysis of the problem can help students a deeper understanding of computer systems in resource sharing, process synchronization, deadlocks and other issues, and skilled use of semaphores to solve the life of the control flow, is about the life of the control flow with formal way to express.)
