ΟΙ ΓΕΥΜΑΤΙΖΟΝΤΕΣ ΦΙΛΟΣΟΦΟΙ – philosophers 42

I’ve never thought philosophy would be so deadly.

Goal

One or more philosophers are sitting at a round table either eating, either thinking, either sleeping. While they are eating, they do not think or sleep; while thinking they don’t eat or sleep; and, of course, while sleeping, they do not eat or think.

• The philosophers sit at a circular table with a large bowl of spaghetti in the center.
• There are some forks on the table. Serving and eating spaghetti with a single fork is very inconvenient, so the philosophers will eat with two forks, one for each hand.
• Each time a philosopher finishes eating, they will drop their forks and start sleeping. Once they have finished sleeping, they will start thinking. The simulation stops when a philosopher dies.
• Every philosopher needs to eat and they should never starve.
• Philosophers don’t speak with each other.
• Philosophers don’t know when another philosopher is about to die.
• No need to say that philosophers should avoid dying!

Arguments

The program should take the following arguments: number_of_philosophers time_to_die time_to_eat time_to_sleep [number_of_times_each_philosopher_must_eat]

• number_of_philosophers: is the number of philosophers and also the number of forks.
• time_to_die: is in milliseconds, if a philosopher doesn’t start eating ’time_to_die’ milliseconds after starting their last meal or the beginning of the simulation, it dies.
• time_to_eat: is in milliseconds and is the time it takes for a philosopher to eat. During that time they will need to keep the two forks.
• time_to_sleep: is in milliseconds and is the time the philosopher will spend sleeping.
• number_of_times_each_philosopher_must_eat: argument is optional, if all philosophers eat at least ’number_of_times_each_philosopher_must_eat’ the simulation will stop. If not specified, the simulation will stop only at the death of a philosopher.
