The resulting networks at 𝑡=2000 for 𝑁=100000, 𝜐=0.0005, 𝛼=0.2, 𝛽=4, 𝛾=4, and 𝑝=0.0001 within an area of 10∗10 grids. (a) The distribution functions of connectivity: for red and green squares, 𝜌(𝜆) is of truncated normal distribution Gauss (𝜇,𝜎²); for blue squares, 𝜌(𝜆) is of uniform distribution Uniform (0, 1). The red, green, and blue lines have respectively slopes 4.02, 2.75, and 2.38. (b) The robustness of obtained networks: for red and green curves, 𝜌(𝜆) is of truncated normal distribution Gauss (𝜇,𝜎²). The red curve has 𝜁=0.82 while the green one has 𝜁=0.76; for blue curve, 𝜌(𝜆) is of uniform distribution Uniform (0, 1) and 𝜁=0.74; purple curve for ER, 𝜁=0.92, and black curve for BA, 𝜁=0.16.
