Reproducibility Variable Result LLM Response
Research Type Experimental We also conduct empirical evaluations of our solution through real data of a major ridesharing platform and show its advantages over fixed pricing schemes as well as several prevalent surgebased pricing schemes.

Pseudocode No The paper does not contain structured pseudocode or algorithm blocks.
Open Source Code No The paper does not provide concrete access to source code for the methodology described.
Open Datasets Yes We perform our empirical analysis based on a public dataset from a major ride-sharing company.3 The dataset includes the orders in a city for three consecutive weeks (Jan. 1st, 2016 – Jan. 21st, 2016) and the total number of orders is more than 8.5 million. [...] 3The dataset is provided by Didi for an algorithm competition.
Dataset Splits No The paper describes how the dataset was processed and used for input (e.g., averages of statistics, estimations), but it does not specify explicit training, validation, or test dataset splits (e.g., percentages or sample counts).
Hardware Specification No The paper mentions being "limited by computing resource" but does not provide specific hardware details such as GPU/CPU models, memory, or specific cloud instance types used for experiments.
Software Dependencies No The paper mentions using "standard gradient descent algorithms" and the "fmincon function" (implying MATLAB), but it does not provide specific version numbers for any software dependencies.
Experiment Setup Yes The length of each timestep is set to be 15 minutes and the number of steps in simulation is 96 (so 24 hours in total). For both FIXED and SURGE, we use the perminute price fitted from data as the base price, α = 0.5117, and allow the surge ratio β to be in [1.0, 5.0].
