abstract = "Generalisation is one of the most important
performance evaluation criteria for artificial learning
systems. An increasing amount of research has recently
concentrated on the robustness or generalisation
ability of the programs evolved using Genetic
Programming (GP). While some of these researchers
report on the brittleness of the solutions evolved,
some others propose methods of promoting
robustness/generalisation. In this paper, a review of
research on generalisation in GP and problems with
brittleness of solutions produced by GP is presented.
Also, a brief overview of several new methods promoting
robustness/generalisation of the solutions produced by
GP are presented.",
