Class 2 Systems

The results of four of the nine new runs (Runs 6-9) were very similar to those reported for the standard run. They had bounded Mean Cumulative Activity ( $\bar{A}_{cum}$), positive Mean New Activity ( $\bar{A}_{new}$), and bounded Diversity (D). At the end of each run, the diversity was very low, with a single dominant genotype and a dozen or fewer mutant genotypes present in much smaller numbers.

The results of Run 7 were slightly different because a mutant of length 372 bits arose which produced an offspring of length 378, which in turn produced an offspring of length 372, and so on in a cycle. However, the general pattern was the same as in Runs 6, 8 and 9.
