Between each pair of philosophers is a single chopstick; a philosopher needs two chopsticks to eat.

WebbEating takes random time, then the philosopher puts the forks down and leaves the dining room. After spending some random time thinking about the nature of the universe, he again becomes hungry, and the circle repeats itself.
