abstract = "Graph based evolutionary algorithms (GBEAs) have been
shown to have superior performance to evolutionary
algorithms on a variety of evolutionary computation
test problems as well as on some engineering
applications. One of the motivations for creating GBEAs
was to produce a diversity of solutions with little
additional computational cost. This paper tests that
feature of GBEAs on three problems: a real-valued
multi-modal function of varying dimension, the
plus-one-recall-store (PORS) problem, and an applied
engineering design problem. For all of the graphs
studied the number of different solutions increased as
the connectivity of the graph underlying the algorithm
decreased. This indicates that the choice of graph can
be used to control the diversity of solutions produced.
The availability of multiple solutions is an asset in a
product realization system, making it possible for an
engineer to explore design alternatives.",
