Figure 3. The friend number’s effects on the average successful trading ratio, market clustering degree and simple social entropy.

With an increase in the number of friends per agent k/N, this model shifts from no information sharing to more information sharing. This figure shows that as k/N increases from 0 to 0.99, the averages of the successful trading ratio D_t and the degree of clustering C_t increase, and the average simple social entropy E_t decreases. The error bars are also shown. All of the averages are calculated after the first 10,000 time-steps.
