Reproducibility Variable Result LLM Response
Research Type Experimental Extensive experimental studies on three applications, Revenue Maximization, Image Summarization, and Maximum Weighted Cut, show that our algorithm not only significantly increases solution quality but also requires comparative adaptivity to state-of-the-art algorithms.

Pseudocode Yes Algorithm 1: AST Algorithm
Open Source Code No The paper does not provide any explicit statements about releasing source code for the described methodology or links to a code repository.
Open Datasets Yes As in the prior work, [Amanatidis et al., 2021], we can construct the graph G using a You Tube community network dataset [Han et al., 2021] with 39,841 nodes and 224,235 edges. As in recent work [Amanatidis et al., 2020], we generate an Erd os-R enyi random graph with 5, 000 nodes and an edge probability of 0.2. As in recent works [Han et al., 2021; Mirzasoleiman et al., 2016], we create an instance as follows: First, randomly sample 500 images from the CIFAR dataset [Krizhevsky, 2019] of 10,000 images
Dataset Splits No The paper mentions using specific datasets but does not explicitly provide details about training, validation, or test dataset splits (e.g., percentages, counts, or references to predefined splits).
Hardware Specification Yes Besides, we experimented on a high-performance computing (HPC) server cluster with the following parameters: partition=large, #threads(CPU)=128, node=4, max memory = 3,073 GB.
Software Dependencies No The paper states 'We used Open MP to program with C++ language' but does not specify version numbers for the programming language or any libraries used.
Experiment Setup Yes In our experiments, we set the accuracy parameter ϵ = 0.1 for all algorithms evaluated, and for AST, we set δ = 0.12.
