Reproducibility Variable Result LLM Response
Research Type Experimental Our extensive experiments demonstrate the effectiveness of LS-MCPP, consistently improving the initial solution returned by two state-of-the-art baseline algorithms that compute suboptimal tree covers on G, with a notable reduction in makespan by up to 35.7% and 30.3%, respectively. To validate the effectiveness of LS-MCPP, we conduct extensive experiments, comparing it with three state-of-the-art baseline graph-based MCPP algorithms that operate on complete terrain graphs only.
Researcher Affiliation Academia Jingtao Tang, Hang Ma Simon Fraser University {jingtao tang, hangma}@sfu.ca
Pseudocode Yes Algorithm 1: LS-MCPP
Open Source Code Yes Code: https://github.com/reso1/LS-MCPP
Open Datasets Yes We use MCPP instances from (Tang and Ma 2023), where their numbers of graph vertices, graph edges, and robots range from 46 to 824, 60 to 1495, and 4 to 12, respectively. As shown in Fig. 6 and Tab. 1, we design three additional larger instances whose terrain graphs are adopted from popular 2D pathfinding benchmarks (Sturtevant 2012).
Dataset Splits No The paper uses specific MCPP instances for evaluation but does not provide details on training, validation, or test dataset splits (e.g., percentages or sample counts).
Hardware Specification Yes This section describes our experimental results on an Intel Xeon Gold 5218 2.30 GHz Linux server with 300 GB memory.
Software Dependencies No The paper does not provide specific version numbers for software components or libraries used in the experiments.
Experiment Setup Yes For all instances solved with LS-MCPP, the pool weight decay factor γ is set to 0.01, and the temperature decay factor α is set to exp log 0.2 M to decrease the temperature t from 1 to 0.2. For instances from (Tang and Ma 2023), we set the max iteration M to 3e3 and the forced deduplication step S to 1e2, For the three additional larger instances in Tab. 1, we set M to 1.5e4 and S to 5e2.
