Random Distribution

Another way in which the distribution of environmental energy can be made non-uniform in Cosmos is to have it distributed randomly. Under this scheme, chunks of energy tokens are distributed to grid positions at random, until the total amount has been allocated.6.6 If the mean number of energy tokens distributed to each grid position was the same as in the standard run (i.e. 30 per time slice), then the populations soon died out. The mean number was therefore increased by threefold to 90 energy tokens per time slice, and the maximum number of energy tokens that any grid position could store was also increased somewhat. Under these conditions, the populations could often survive for reasonable durations. The non-default parameter settings for these experiments are shown in Table 6.10.
