* Development and empirical test of different communication schemes among colonies
  +
<pre>
  +
The i.a.k identify how often we do communication among colonies.
  +
  +
The law used to generate the periods is SQRT[(10)^(i+1)], so
  +
i = 1 --> T = 10
  +
i = 2 --> T = 31
  +
i = 3 --> T = 100
  +
i = 4 --> T = 316
  +
i = 5 --> T = 1000
  +
i = 6 --> T = 3162
  +
i = 7 --> T = 10000
  +
i = 8 --> T = 31622
  +
i = 9 --> T = 100000
  +
  +
The jth exchange happens at iteration
  +
  +
  +
T * (1 - 0.a^j)/(1 - 0.a) IF (int)[x_j - x_(j-1)] > k
  +
x_j =

k OTHERWISE
