Abstract:

Genetic Improvement (GI) uses modern search and optimisation
techniques, principally Genetic Programming (GP), to optimise
existing programs.  I will start with a very brief introduction
to GP, particularly its use in evolving optimisation benchmarks,
hyper-heuristics, network protocols, composing web services,
cache management strategies, specialising hashing and malloc,
redundant programming and automatic bugfixing.  There are many
ways to balance requirements against resources (such as CPU,
memory and energy consumption), but we cannot try them all. Also
the easiest program to write (and maintain) may not be the most
accurate or give the best trade-off between speed and
quality. Then again the Pareto optimal tradeoff may be different
on each hardware platform and it may change with time. Potentially
GI could automatically customise apps for different users, even
for different times of the day for the same user.

Mostly I will concentrate on examples, such as were GI
automatically customised existing programs to give considerable
speed ups by evolving a new version of the program tailored to
special cases.
