Pseudocode Yes Algorithm 1: Generalized Greedy Algorithm; Algorithm 2: Adaptive Generalized Greedy Algorithm; Algorithm 3: POMC Algorithm
Open Source Code No The paper states: 'We thank Chao Qian for providing his POMC implementation and test data to carry out our experimental investigations.' This indicates they used code provided by others, not that they are releasing their own code. No link or statement about code release is provided.
Open Datasets Yes To consider the cardinality constraint, we use the social news data which is collected from the social news aggregator Digg. ... (Hogg and Lerman 2012).
Dataset Splits No The paper does not provide specific details on dataset splits (e.g., percentages or counts for training, validation, or testing sets) required for reproducibility in the context of data partitioning for model training.
Hardware Specification No The paper does not specify any hardware details such as CPU/GPU models, memory, or specific computing environments used for the experiments.
Software Dependencies No The paper does not provide specific software dependencies or their version numbers (e.g., programming languages, libraries, or solvers with version numbers).
Experiment Setup Yes We assume that the initial constraint bound is B = 10 and stays within the interval [5, 30]. We consider a sequence of 200 constraint bounds obtained by randomly increasing or decreasing B by a value of 1. The values of B over time used in our studies are shown in Figure 2. For the experimental investigations of POMC, we consider a parameter τ which determines the number of generations between constraint changes. Furthermore, we consider the option of POMC having a warm-up phase where there are no dynamic changes for the first 10000 iterations.
