Supplement for "Aesop: White-Box Best-First Proof Search for Lean"

This is the supplement for the paper "Aesop: White-Box Best-First Proof Search for Lean", presented at CPP 2023.

There are two ways to use this artifact:

• aesop.tar.gz contains the source code of the version of Aesop discussed in the paper, as well as the test suite and a script for evaluating the case studies. After you've unpacked this archive, follow the instructions in the README to set up Lean 4, build Aesop and evaluate the case studies.
• aesop-artifact.ova is a virtual machine (running a Debian 11 Linux system with an LXQt desktop environment) which provides a full Lean 4 environment, including the Visual Studio Code text editor with the Lean 4 extension pre-installed. To access the virtual machine, run it (with e.g. VirtualBox, VMWare or QEMU) and log in as user "artifact" with password "password". The folder /home/artifact/aesop contains the contents of aesop.tar.gz, including the README with further instructions. You can skip the "Building Aesop" section of the README since we have already performed these steps for you. To start Visual Studio Code, click on the corresponding Desktop icon; this should automatically open the Aesop folder and start the Lean 4 server. If you need root access, use sudo with password "password".

This version fixes a minor configuration issue with the VM and is otherwise identical to version 1.
