Pseudocode Yes Algorithm 1 returns whether the set S of targets can be scheduled in night j Require: Targets S sorted by non-decreasing meridians 1: ctime 0 2: for each target i 2 S do 3: ctime max(ctime, rj i 4: if ctime > dj i then 5: return false; 6: return true
Open Source Code No The paper does not provide any concrete access to source code (no repository link, explicit code release statement, or code in supplementary materials) for the methodology described.
Open Datasets No Since we only have one real dataset, we generated realistic random datasets.
Dataset Splits No The paper mentions using 'real and realistic datasets' but does not provide specific dataset split information (exact percentages, sample counts, citations to predefined splits, or detailed splitting methodology).
Hardware Specification Yes The experiments were performed on an Intel Xeon E52440 v2 @ 1.9 GHz processor and 32 GB of RAM, and ran with a memory limit of 4 GB and a time limit of 2 hours.
Software Dependencies No The paper does not provide specific ancillary software details (e.g., library or solver names with version numbers) needed to replicate the experiment.
Experiment Setup No The paper describes the general experimental environment (hardware, datasets) and evaluation metrics, but does not provide specific experimental setup details such as hyperparameter values or training configurations for the algorithms.
