Reproducibility Variable Result LLM Response
Research Type Experimental Simulation results over IEEE test cases show that it outperforms existing strong DNN baselines in ensuring 100% feasibility and attaining consistent optimality loss (<0.19%) and speedup (up to 228) in both light-load and heavy-load regimes, as compared to a state-of-the-art solver.

Pseudocode Yes Algorithm 1: Determining Sufficient DNN Size
Open Source Code No The paper does not contain an explicit statement about releasing its source code or a link to a code repository.
Open Datasets Yes We evaluate its performance over IEEE 30-/118-/300bus test cases (tpc, 2018) on the input load region of [100%, 130%] of the default load covering both the light-load ([100%, 115%]) and heavy-load ([115%, 130%]) regimes, respectively. (tpc, 2018) refers to Power Systems Test Case Archive, 2018. http://labs.ece.uw.edu/pstca/.
Dataset Splits No The paper mentions 'training set' and 'test setting' but does not provide specific details on training, validation, and test splits (e.g., percentages or exact counts) needed for reproduction.
Hardware Specification Yes We conduct simulations in Cent OS 7.6 with a quad-core (i7-3770@3.40G Hz) CPU and 16GB RAM.
Software Dependencies No The paper mentions software like 'Pypower' and 'Gurobi' but does not provide specific version numbers for these or any other key software dependencies.
Experiment Setup Yes The paper describes the loss function (Equation 11) with weighting factors w1 and w2. A footnote in Table 1 states: 'The training epochs for the other DNN schemes are 200'.
