dxt/dt=rxxt-axtyt , dyt/dt=bxtyt-cyt

This model describes an interspecific predator-prey relationship. The base model of prey's growing is exponential growth model. The prey(X)'s population is x, and the predator(Y)'s population is y.


rx : Intrinsic Rate of Natural Increace of Prey

a : The average number of eaten prey per one pedator

b : The average required number of eaten prey per one birth of pedator

c : The average death rate of pedator

x0 & y0 : Initial Population
