Phase portrait. (a), (b) 2-dimensional phase portrait of almost periodic system (13). Time-series 𝑥^∗₁(𝑛) and 𝑥^∗₂(𝑛) with initial values 𝑥^∗₁(0)=1.19, 𝑥^∗₂(0)=1.18 for 𝑛∈[0,100] and 𝑛∈[700,800], respectively. (c), (d) 3-dimensional phase portrait of almost periodic system (13). Time-series 𝑥^∗₁(𝑛) and 𝑥^∗₂(𝑛) with the above initial values for 𝑛∈[0,100] and 𝑛∈[700,800], respectively.
