Reproducibility Variable Result LLM Response
Research Type Experimental Experiments Bayesian Network Scores We start the experiments by comparing the BDeu scores of structures learned by the proposed method against scores from the state-of-the-art approaches.

Pseudocode Yes Algorithm 1 Find the optimal k-tree given an initial (k+1)clique. and Algorithm 2 Learning a Bayesian network structure of bounded tree-width.
Open Source Code No The paper states 'The implementation of the proposed algorithm is in Matlab', but it does not provide any link or explicit statement that its source code for the described methodology is publicly available.
Open Datasets Yes We use a collection of data sets from the UCI repository (Bache and Lichman 2013) of varying dimensionalities
Dataset Splits No The paper mentions generating samples and using datasets but does not provide specific training/validation/test split percentages, sample counts, or references to predefined splits for reproduction.
Hardware Specification Yes The implementation of the proposed algorithm is in Matlab on a desktop with 16GB of memory.
Software Dependencies No The paper states 'The implementation of the proposed algorithm is in Matlab', but it does not provide any version number for Matlab or other specific software libraries/solvers used.
Experiment Setup Yes In all experiments, we maximize the Bayesian Dirichlet equivalent uniform (BDeu) score with equivalent sample size equal to one (Heckerman, Geiger, and Chickering 1995). It has been given ten minutes of running time, same that was given to all other approximate algorithms. The exact methods (MILP and GOBNILP) are given three hours of running time. The iteration limit is set to 100 with different initial cliques.
