Research Type Experimental Experimental results on PMS benchmarks from Max SAT Evaluation 2013 show that Dist significantly outperforms state-of-the-art PMS algorithms, including both local search algorithms and complete ones, on random and crafted benchmarks. For the industrial benchmark, Dist dramatically outperforms previous local search algorithms and is comparable with complete algorithms. Experimental Evaluation We empirically evaluate Dist on all Partial Max SAT benchmarks in Max SAT Evaluation 2013, including three categories namely random, crafted and industrial.

Pseudocode Yes Algorithm 1: Dist Input: Partial Max SAT instance F, max Steps α := randomly generated truth assignment; 1 cost := + ; 2 for step := 1 to max Steps do 3 if falsified hard clauses & cost(α) < cost then 4 α := α; cost := cost(α);
Open Source Code No Dist is implemented in C++ and complied by g++ with the O2 option, and will be distributed online.
Open Datasets Yes We empirically evaluate Dist on all Partial Max SAT benchmarks in Max SAT Evaluation 2013, including three categories namely random, crafted and industrial.
Dataset Splits No The paper mentions using Partial Max SAT benchmarks from Max SAT Evaluation 2013 but does not explicitly state specific training, validation, or test dataset splits (e.g., percentages or sample counts). The evaluation is done on pre-defined benchmark sets.
Hardware Specification Yes All experiments are carried out on a workstation under Ubuntu Linux operation system, using an Intel(R) Core(TM) i7-2640M 2.8 GHz CPU and 8 GB RAM.
Software Dependencies No The paper states that Dist is implemented in C++ and compiled by g++ with the O2 option, but it does not provide specific version numbers for C++ compiler (g++) or any other software libraries.
Experiment Setup Yes The sp parameter for the weighting scheme is set to 0.0012.2 (Footnote 2: except that 0.0001 for industrial instances with more than 2500 variables).
