This file calculates the birth rate, death rate, and population of rabbits.

rabbit_births[ t ] is the number of rabbits born during time t.

table rabbit_births : time -> general. rabbit_births[ t ] = number_of_rabbits[ t ] * birth_rate_of_rabbits[] * ( 1 - number_of_rabbits[ t ] / limit_of_rabbit_population[] ) * 0.01.

rabbit_deaths[ t ] is the number of rabbits killed during time t.

table rabbit_deaths : time -> general. rabbit_deaths[ t ] = number_of_rabbits[ t ] * death_rate_of_rabbits[] * number_of_foxes[ t ] * 0.0005.

number_of_rabbits[ t ] is the population of rabbits at time t.

table number_of_rabbits : time -> general. number_of_rabbits[ 1 ] = initial_number_of_rabbits[]. number_of_rabbits[ t>1 ] = number_of_rabbits[ t-1 ] + rabbit_births[ t-1 ] - rabbit_deaths[ t-1 ].

initial_number_of_rabbits[] is the rabbit population at time 1. This is input by the user.

table initial_number_of_rabbits : -> general. initial_number_of_rabbits[] = 1000.

birth_rate_of_rabbits[] is the proportion of rabbits born in a year. It is input by the user.

table birth_rate_of_rabbits : -> general. birth_rate_of_rabbits[] = 5.

death_rate_of_rabbits[] is the proportion of rabbits that die in a year. It is input by the user.

table death_rate_of_rabbits : -> general. death_rate_of_rabbits[] = 5.

limit_of_rabbit_population[] is the maximum number of rabbits allowed. This is input by the user.

table limit_of_rabbit_population : -> general. limit_of_rabbit_population[] = 10000.
