Figure
1 a,
bifurcation and b, complementation.
The complementary region and noncomplementary region are marked by C and U,
respectively. P represents complementary critical point(r = 3.593). L(r = 3.589)
and R(r = 3.597) are selected values
of r to compare forecasts in the complementary
region and noncomplementary region in figure 2 and 3. It is clearly seen that
in complementary region, each population occupies only one branch, and so the
two populations both are stabilized.
