We study the problem of learning the best Bayesian network structure with\nrespect to a decomposable score such as BDe, BIC or AIC. This problem is known\nto be NP-hard, which means that solving it becomes quickly infeasible as the\nnumber of variables increases. Nevertheless, in this paper we show that it is\npossible to learn the best Bayesian network structure with over 30 variables,\nwhich covers many practically interesting cases. Our algorithm is less\ncomplicated and more efficient than the techniques presented earlier. It can be\neasily parallelized, and offers a possibility for efficient exploration of the\nbest networks consistent with different variable orderings. In the experimental\npart of the paper we compare the performance of the algorithm to the previous\nstate-of-the-art algorithm.
