abstract = "Removing unnecessary instructions is commonly
performed in a sequential single backward slice through
the whole program from the output to its inputs. By
keeping track of all registers the program can be
broken into 100 or more sections which can each be
simplified in parallel. In large evolved linear genetic
programming (GP) programs the reduction in intron
anti-bloat removal overhead (9.7 fold) can exceed the
time to interpret the program, giving effective speeds
of up to 726 billion GP operations/second (726
GigaGPOP/s).",
