| Research Type | Experimental | We provide an empirical evaluation in 6, showing that rerooting can be particularly effective for models with dense, strong edges and weak singleton potentials. Section 6. Experiments: We ran experiments on the following topologies and model sizes: complete graphs on 10 and 15 variables; grids of size 5 x 5 and 9 x 9. All potentials were drawn randomly. |

| Pseudocode | No | The paper does not contain any pseudocode or algorithm blocks. |
| Open Source Code | No | The paper states 'All methods were implemented using lib DAI (Mooij, 2010)' which is a third-party library, but does not provide access to the authors' own source code for the methodology described in the paper. |
| Open Datasets | No | The paper evaluates inference methods on graphical models with specified topologies (complete graphs, grids) where potentials were drawn randomly. It does not use a fixed, publicly available dataset with a training set in the typical sense. |
| Dataset Splits | No | The paper evaluates inference methods on graphical models with specified topologies and random potentials. It does not refer to traditional train/validation/test splits as it is not a supervised learning task on a fixed dataset. |
| Hardware Specification | No | The paper does not provide any specific details about the hardware used to run the experiments (e.g., GPU models, CPU types, memory). |
| Software Dependencies | Yes | All methods were implemented using lib DAI (Mooij, 2010), see the Appendix 9 for details. |
| Experiment Setup | Yes | All potentials were drawn randomly: mixed models used Wij U[ Wmax, Wmax], attractive models used Wij U[0, Wmax], as Wmax was varied; singleton potentials were drawn either from a low range θi [ 0.1, 0.1], medium range θi [ 2, 2], or from a range commensurate with edge potentials, i.e. θi U[ Wmax/2, Wmax/2], with the factor of 2 needed given the form of (1). |
