## Figure 4.
Effects of interaction strength on the stability of the dynamic network with different
interaction matrix ( Figure 4 shows the evolutionary dynamics with interaction matrix as [0 1; 1 0], k=4, and initial
populations of type P ∈ (0, 1))_{A}A and C cells are set as 9900 and 100 in a total population of 10000, respectively. The intensity
of selection ω equals to 0.01. Variable Ṗ is negative when the initial status of _{A}P stays in the region between the marked root (red square) and 1 in the left part of
the figure(Left). When _{A}P goes to the marked root, _{A}Ṗ reaches 0. Accordingly, the population of type _{A}A cells decreases in the interval of [root, 1] until P goes to the root denoted at 0.5 in the simulation. The simulation results shown in
the right part of the figure (Right) demonstrate that the population of type _{A}A cells approached 5000 within 1000 generations.
