Lotka–Volterra Model

A pair of coupled ordinary differential equations that model interacting populations (commonly predator and prey or competing species) by combining intrinsic growth or decay rates with bilinear interaction terms proportional to the product of population sizes.

A system of coupled nonlinear ordinary differential equations describing interacting populations (commonly predator and prey or competing species) with bilinear interaction terms, for example ẋ = αx − βxy, ẏ = −γy + δxy for a predator–prey pair, capturing reciprocal growth and removal.
