Pseudocode Yes Algorithm 1 k-fold cross-validation
Open Source Code No The paper does not provide an explicit statement or link for the open-source code of its methodology.
Open Datasets Yes The real-world retail dataset used in (Ito & Fujimaki, 2017; 2016) contains sales information for a middle-size supermarket located in Tokyo.4
Dataset Splits Yes We used the first 35 months (1063 samples) for training regression models and simulated the best price strategy for the next day 2014/12/1.
Hardware Specification No The paper does not provide specific hardware details such as GPU or CPU models used for running the experiments.
Software Dependencies Yes We used GUROBI Optimizer 6.0.43 for portfolio optimization, and the algorithm in (Ito & Fujimaki, 2016) for price optimization.
Experiment Setup Yes We chose D = 50, N = 20, and λ = 1.0 for our simulation experiments.
