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.
