Artifact Submission Title of paper: Compositional Design, Implementation, and Verification of Swarms ECOOP submission number for paper: #44 Our paper presents theory and techniques for the compositional specification, implementation and verification of swarm protocols, and for the composition of swarms. This artifact comprises a Docker image containing: our custom open-source extension of the Actyx toolkit supporting the theory presented in the paper, scripts to reproduce the experimental results presented in the paper, and several example swarms implemented using our tool. The swarms can be executed and their source code can be edited. To run the artifact please download swarm-artifact.tar.gz, extract its contents and follow the README in the extracted archive.
