Evolving dynamics of a model society.


<p>We set <i>n</i> to 100, while <i>a/b</i>, <i>p<sub>c</sub></i>, and <i>p<sub>m</sub></i>, are assigned two optional values each, which are: <i>a/b</i>1 = 60, <i>a/b</i>2 = 120; <i>p<sub>c</sub></i>1 = 0.1, <i>p<sub>c</sub></i>2 = 0.4; <i>p<sub>m</sub></i>1 = 0.01, <i>p<sub>m</sub></i>2 = 0.04. All of the 8 combinations of these parameter values are used for the simulation, and each combination is run with 50 replications. The mean and standard deviation of total productivity and number of occupations of the society are shown. Each combination is termed with four numbers in the figure label, (<i>e.g.</i>, 111 refers to the parameter combination “<i>a/b</i>1, <i>p<sub>c</sub></i>1, <i>p<sub>m</sub></i>1”, while 221 refers to the combination “<i>a/b</i>2, <i>p<sub>c</sub></i>2, <i>p<sub>m</sub></i>1”, <i>etc</i>). The 4 final productivity values revealed in the figure correspond to the 4 different combinations of <i>a/b</i> and <i>p<sub>c</sub></i>, while for each of these combinations, the larger <i>p<sub>m</sub></i> value corresponds with the short transition time.</p
