Pseudocode Yes Algorithm 1 Ψ-Saturate Algorithm Input: MMMs Π, steps K, budget L, precision ϵ, param. β. Output: Reward Placement S R of cost at most βL.
Open Source Code Yes We implemented6 all methods in C++ 17 and ran experiments on a 376GB server with 96 CPUs @2.6GHz. 6https://anonymous.4open.science/r/RRP-F6CA
Open Datasets No We use two different types of synthetic datasets to represent stochastic networks (i.e., MMMs). In each type, we generate a directed graph and then sample edge weights from a normal distribution to create different settings. We gathered movement records from Baidu Map, covering Xuanwu District in Nanjing from July 2019 to September 2019; The paper does not provide a specific link, DOI, or formal citation for public access to these datasets.
Dataset Splits No The paper does not explicitly provide details about training, validation, or test dataset splits; it describes synthetic data generation and usage of real-world data without specifying these partitions.
Hardware Specification Yes We implemented6 all methods in C++ 17 and ran experiments on a 376GB server with 96 CPUs @2.6GHz.
Software Dependencies No The paper states “We implemented6 all methods in C++ 17” but does not list specific versions for any other software dependencies, libraries, or solvers used in the experiments.
Experiment Setup Yes We use different problem parameters as Table 1 shows, marking the default value of each parameter in bold. To satisfy the budget constraint for the Ψ-Saturate algorithm, we fix β = 1 as in Corollary 7 and set precision to ϵ = (|Π| 103) 1. We set the budget L as a percentage of the total cost P s S c[s].
