abstract = "Using the language independent genetic improvement
tool MAGPIE (Machine Automated General Performance
Improvement via Evolution of software), we measure the
impact of GI on a non-deterministic deeply nested
PARSEC VIPS parallel computing multi-threaded image
processing benchmark written in C. More than 53% of
mutants compile and generate identical output. Overall
we find approximately 10% Failed Disruption Propagation
(FDP). Excluding software detected internal errors and
asserts, almost all changes deeper than 30 nested
functions which are Executed and Infect data or change
control are not Propagated. That is, almost all deep
PIE code changes have no external impact. Suggesting
(where it relies on testing) automatic software
engineering on deeply nested code will be hard.",
