The Effects of Decision-Making Processes and Population Turnover on the Formation of Social Networks

Figure 4

The grid distance and age difference between connected nodes at 𝑡=2000 for 𝑁=20000, 𝜐=0.0005, and 𝑝=0.0001 and 𝜌(𝜆) is of truncated normal distribution with 𝜇=0.5, 𝜎=0.20 within an area of 10∗10 grids. In (a), (b), and (c), the color denotes the proportion of node pairs with grid distance (𝑥,𝑦) in total nodes pairs. All of them use 𝛼=0.2 and 𝛽=4, while 𝛾=0 for (a), 10 for (b), and 20 for (c). (d) The age difference between connected node pairs uses 𝛼=0.2, 𝛾=4, and different 𝛽 (see the legend 𝛼-𝛽-𝛾). The horizontal axis denotes age difference, while the vertical axis denotes the proportion of node pairs with age difference 𝑎_𝑖𝑗 in total node pairs.
