  abstract =     "Since its inception, pige has used evolution to guide
                 the order of how to construct derivation trees. It was
                 hypothesised that this would allow evolution to adjust
                 the order of expansion during the run and thus help
                 with search. This research aims to identify if a
                 specific order is reachable, how reachable it may be,
                 and goes on to investigate what happens to the
                 expansion order during a piGE run. It is concluded that
                 within pige we do not evolve towards a specific order
                 but a rather distribution of orders. The added
                 complexity that an evolvable order gives pige can make
                 it difficult to understand how it can effectively
                 search, by examining the connectivity of the phenotypic
                 landscape it is hoped to understand this. It is
                 concluded that the addition of an evolvable derivation
                 tree expansion order makes the phenotypic landscape
                 associated with pige very densely connected, with
                 solutions now linked via a single mutation event that
                 were not previously connected.",
