Solutions of the Lotka-Volterra equations obtained by a fourth-order Runge-Kutta algorithm, for parameters α=2/3{\displaystyle \alpha =2/3}, β=4/3{\displaystyle \beta =4/3}, γ=1{\displaystyle \gamma =1} and δ=1{\displaystyle \delta =1}. Initial conditions (circle symbols) vary from 0.9{\displaystyle 0.9} to 1.8{\displaystyle 1.8} with 0.1{\displaystyle 0.1} step.
