Dataset Card for Dataset Name

This dataset contains 1 billion observation-action pairs to clone the behavior of LaCAM approach to solve MAPF problem via transformer (GPT) model.

Dataset Details

Dataset Structure

Dataset contains train and validation parts.

  • train part contains 1,000 * 2^20 obsevation-action pairs. They are divided into 500 .arrow files.
  • validation part contains 2^20 observation-action pairs. They are saved into a single .arrow file. Dataset requires 256 GB of disk space.

More details about creation of the dataset, the source data, the structure of observation, etc. are provided in the paper
