  abstract =     "In genetic programming, the size of a solution is
                 typically not specified in advance and solutions of
                 larger size may have a larger benefit. The flexibility
                 often comes at the cost of the so-called bloat problem:
                 individuals grow without providing additional benefit
                 to the quality of solutions, and the additional
                 elements can block the optimisation process.
                 Consequently, problems that are relatively easy to
                 optimise cannot be handled by variable-length
                 evolutionary algorithms.

                 In this article, we analyse different single- and
                 multi-objective algorithms on the sorting problem, a
                 problem that typically lacks independent and additive
                 fitness structures. We complement the theoretical
                 results with comprehensive experiments to indicate the
                 tightness of existing bounds, and to indicate bounds
                 where theoretical results are missing.",
