Bayesian networks (BNs) constitute a useful tool to model the joint
distribution of a set of random variables of interest. This paper is
concerned with the network induction problem. We propose a number of hybrid
recombination operators for extracting BNs from data. These hybrid operators
make use of phenotypic information in order to guide the processing of
information during recombination. The performance of these new operators is
analyzed with respect to that of their genotypic counterparts. It is shown
that these hybrid operators provide notably improved and rather robust
results. Some remarks on the future of the area are also laid out.
