Numerical simulations of mean degree. (a) A simplified period-50, period-100, period-200 and period-250 time series of 1000 data. (b) The mean degree of the resulting LPHVGs with different ρ, where the time series with periodic-50, periodic-100, periodic-200 and periodic-250 are represented by circles, triangles, squares and diamonds, respectively. The solid lines correspond to the theoretical result for each time series.
