Reproducibility Variable Result LLM Response
Research Type Experimental We conduct the experiments on courier dispatching problem, and the results show that Dec-SGTS achieves much better reward while enjoying a significant reduction of planning time and communication cost compared with Dec-MCTS (Decentralized Monte Carlo Tree Search).

Pseudocode Yes Algorithm 1 Dec-SGTS for agent i" and "Algorithm 2 Expansion with Subgoal States
Open Source Code Yes For formalization and proof, see supplementary material https://github.com/HPCL-micros/dec-sgts.
Open Datasets No The paper mentions using "CDP benchmark" and shows examples from "Amap" and "CDP grid world" but does not provide a direct link, DOI, specific repository name, or formal citation for accessing the dataset used in experiments.
Dataset Splits No No specific dataset split information (exact percentages, sample counts, citations to predefined splits, or detailed splitting methodology) is provided.
Hardware Specification Yes Dec-SGTS is implemented with a platform of 12 cores, 3.7 GHz and 16 GB Memory.
Software Dependencies No No specific ancillary software details, such as library or solver names with version numbers, are provided.
Experiment Setup Yes Agent moves for one grid with reward -0.01 and picks up a package with reward 1.0. For each experiment, we use different settings and parameters. Given planning time of 15 seconds. We use the action coverage threshold σ to expand tree nodes with subgoal states.
