abstract = "Neutral networks in biology often contain diverse
solutions with equal fitness, which can be useful when
environments (requirements) change over time. we
present a method for studying neutral networks in
software. In these networks, we find multiple solutions
to held-out test cases (latent bugs), suggesting that
neutral software networks also exhibit relevant
diversity. We also observe instances of positive
epistasis between random mutations, i.e. interactions
that collectively increase fitness. Positive epistasis
is rare as a fraction of the total search space but
significant as a fraction of the objective space:
9percent of the repairs we found to look (and
4.63percent across all programs analysed) were produced
by positive interactions between mutations. Further,
the majority (62.50percent) of unique repairs are
instances of positive epistasis",
