abstract = "New constructive algorithms for the two-dimensional
guillotine-cutting problem are presented. The
algorithms were produced from elemental algorithmic
components using evolutionary computation. A subset of
the components was selected from a previously existing
constructive algorithm. The algorithms' evolution and
testing process used a set of 46 instances from the
literature. The structure of three new algorithms is
described, and the results are compared with those of
an existing constructive algorithm for the problem.
Several of the new algorithms are competitive with
respect to a state-of-the-art constructive algorithm. A
subset of novel instructions, which are responsible for
the majority of the new algorithms' good performances,
has also been found.",
