Research Type Experimental We then observe that the theory is predictive of what will occur empirically. We show on graphs where terminals are drawn from a distribution, the new online algorithms have strong performance even with modestly correct predictions. [...] This section investigates the empirical performance of the proposed algorithm OAPT and IOAPT for the undirected Steiner tree problem.

Pseudocode No The paper describes algorithms step-by-step but does not present them in a formal pseudocode block or algorithm box.
Open Source Code Yes The code is available at https://github.com/Chenyang-1995/Online-Steiner-Tree
Open Datasets Yes The road network of Bay Area is provided by The 9th DIMACS Implementation Challenge... We will sample s training instances of k terminals T1, T2, . . . Ts.
Dataset Splits No The paper describes how training instances are used for a learning algorithm and selection of a parameter, but does not provide specific train/validation/test splits with percentages or sample counts for the main experiment evaluation.
Hardware Specification Yes The experiments are conducted on a machine running Ubuntu 18.04 with an i7-7800X CPU and 48 GB memory.
Software Dependencies No The paper mentions the operating system (Ubuntu 18.04) but does not provide specific version numbers for any other software dependencies or libraries used.
Experiment Setup Yes We only consider θ {0, 0.2, 0.4, 0.6, 0.8, 1}.
