How to solve Dining Philosopher's Problem?

A Classic Synchronization Problem in Computer Science

The Dining Philosophers Problem is a classic computer science problem that explores synchronization and resource allocation in a concurrent system.

The Setup- Five philosophers sit at a circular table with a bowl of spaghetti and five chopsticks.

To design an algorithm that allows philosophers to eat & think alternately without any of them starving, given that a philosopher needs both chopsticks on his left & right to eat.

Problem Statement

The problem was structured to address the problem of deadlocks that can arise when multiple resources are shared in an operating system.

Wondering what is a deadlock?

Why the problem was structured?

Let’s consider the philosophers as P0, P1, P2, P3, P4, & chopsticks as C0, C1, C2, C3, C4.   Algorithm   1. P0 enters the process and acquires resources C0 and C1 as no other process is in the system.

2. Now, process P1 enters the system. It waits for C1 to be freed by P0, then acquires C1 and C2.

Time Complexity: O(N), where N is the number of processes or philosophers.
