Which parameters influence Bayesian score ?

I am trying to compare several models derived via the Bayesian search procedure in GeNie, and I am not sure which search parameter values will influence the Bayesian score of the resulting structure. For example, if I obtain a particular graphical structure with one particular choice of link probabi...

I virtually always seem to get a TREE structure (i.e., branching, but no 'loops') when using a score-based method such as the Bayesian search (which uses the BDeu score). Is this typical for score-based methods ? With the same data, the constraint-based methods (such as the PC algorithm variants) ar...
