Reproducibility Variable Result LLM Response
Research Type Experimental Experimental Results All our experiments were run on a Linux machine with an Intel Xeon CPU E5-2630 v2 running at 2.60GHz, with memory usage limited to 8GB. We used Gurobi 8.1.1 to solve the MIP models of the MVCs of the various heuristics. We experimented on the MAPF benchmark (Stern et al. 2019), which contains 32 grids of different types (city maps, grids with random obstacles, mazes, warehouse maps, etc.), each with 25 scenarios that specify the start and target locations for up to 7,000 agents.

Pseudocode No The paper describes methods and processes but does not contain any structured pseudocode or algorithm blocks.
Open Source Code Yes Our code is available at https://github.com/eli-b/fcardinal.
Open Datasets Yes We experimented on the MAPF benchmark (Stern et al. 2019)
Dataset Splits No The paper refers to the 'MAPF benchmark (Stern et al. 2019)' and its 'scenarios' but does not specify explicit train/validation/test dataset splits (percentages, counts, or specific methods like k-fold cross-validation) for their experiments.
Hardware Specification Yes All our experiments were run on a Linux machine with an Intel Xeon CPU E5-2630 v2 running at 2.60GHz, with memory usage limited to 8GB.
Software Dependencies Yes We used Gurobi 8.1.1 to solve the MIP models of the MVCs of the various heuristics.
Experiment Setup Yes We increased the number of agents on these scenarios until we reached the runtime limit of 60 seconds. For higher numbers of agents, the solver was considered to have failed implicitly. The baseline solver in all of our experiments was only aware of g-cardinal conflicts, used the CG heuristic, and implemented bypassing conflicts (Boyarski et al. 2015a).
