abstract = "This paper deals with genetic programming-based
improvement of non-functional properties of programs
intended for low-cost microcontrollers. As the
objective is to significantly reduce power consumption
and execution time, the approximate computing scenario
is considered in which occasional errors in results are
acceptable. The method is based on Cartesian genetic
programming and evaluated in the task of approximation
of 9-input and 25-input median function. Resulting
approximations show a significant improvement in the
execution time and power consumption with respect to
the accurate median function while the observed errors
are moderate.",
