About dining philosophers problem

The diagram above represents the problem. There are five silent philosophers (P1 – P5) sitting around a circular table, spending their lives eating and thinking.

There are five forks for them to share (1 – 5) and to be able to eat, a philosopher needs to have forks in both his hands. After eating, he puts both of them down and then they can be picked by another philosopher who repeats the same cycle.

Goal

The goal is to come up with a scheme that helps the philosophers achieve their goal of eating and thinking without getting starved to death.
