操作系统课程设计-哲学家进餐问题精编版优化方案

The document "Operating System Course Design - The Dining Philosophers Problem Refined Version" provides a detailed description of the dining philosophers problem, a classic synchronization problem in computer science. The problem involves a group of philosophers sitting around a circular table with chopsticks between each pair of philosophers. The philosophers alternate between thinking and eating, but can only eat when they have both chopsticks. The document outlines a refined version of the problem, where several groups of philosophers are introduced. Each group has three philosophers, labeled as a, b, and c, with two vertical boxes between each pair of philosophers. The document provides specific instructions for accurately measuring the distances between the philosophers and the vertical boxes to ensure proper installation. The process involves taking 2 to 3 measurements, comparing the values to the design measurements, and adjusting the vertical installation accordingly. It emphasizes the importance of precision and accuracy in measurements, especially when dealing with errors in the horizontal and vertical dimensions. Overall, the document provides a comprehensive guide for tackling the dining philosophers problem in a systematic and detailed manner. It highlights the importance of meticulous planning and execution in solving synchronization problems in operating systems.
