[idoby]

This seems like a very interesting package! I will have the time to dive in more in-depth soon, but in the meanwhile, can the authors fix the citation on line 17 of the paper to be consistent with the other citations, and resolve the invalid citation issue?

Also, please clarify the contributions of the two extra authors who are not listed as collaborators on the GitHub repo.

Thanks!

Apologies if these contribution edits should have been made in the manuscript?

• Dmitry Duplyakin contributed documentation for running graph-env on AWS, and debugged a lot of that workflow (Add config and doc for TSP on Ray at AWS NREL/graph-env#22).
• Jeffrey Law has contributed extensively to downstream repositories NREL/rlmolecule, and his feedback has been helpful in the direction of this more general-purpose library

That invalid DOI, 10.1038/s42256-022-00506-3, should be live starting 04 August 2022 at 11:00 (US Eastern Time)

I'm pretty new at reviewing for JOSS, but the documentation does not state this information has to be specified in the manuscript. So I think just your comment should be fine.

That invalid DOI, 10.1038/s42256-022-00506-3, should be live starting 04 August 2022 at 11:00 (US Eastern Time)

OK, LGTM then. Appreciate your work on the library and thank you for contributing it. :)

[idoby]

@pstjohn Looking at it now, it seems like the merge commit for Dmitry's PR prevented him being listed as a contributor by GitHub. I'm not sure why, since it usually works fine.

[Viech]

I have completed my review with some remarks below and will tick my remaining boxes when these points were addressed or discussed. Overall, I find that this is a small but nicely maintained and documented package whose scope could be described a bit better to a non-specialist audience.

General checks

Substantial scholarly effort

Functionally this is a very small library: Excluding the examples subfolder, there are significantly less than 1000 lines of code in the graphenv folder that appears to contain the library as such, so I should flag this to @osorensen. This code gives the impression of a joint wrapper around two existing libraries. On the other hand, a substantial effort is apparent in the presentation and integration of this code in the form of tests, examples, and deploymet scripts. I can also see that the functionality offered is useful and not accessible to users not familiar with the backend libraries used.

Functionality

Installation

• I have opened #36.

Documentation

A statement of need

• JOSS asks for the target audience to be mentioned in the documentation.

Installation instructions

• The dependencies are handled by pip but it would be good to have them listed also in the documentation (for working with the source and for external package managers).
• It appears that one can choose between tensorflow and torch, with one of them being required. This is not documented in the "Installation" section.

Manuscript

I find that the manuscript is well-written and concise but the distinction between graph search problems and other problem representations could be made more clear as this seems to be the selling point for the software.

Author list

• If possible with the template, you should use inter-word spacing between "St." and "John".
• If possible, the digit 2 and the pilcrow in the author affiliations would look better on the respective next line, before their associated text. (Also, I would expect some contact info for the corresponding author; was this missed or is it not intended?)

Summary

• The concept of "strong relational inductive biases" is not made clear to a general audience.
• It would be nice to get an intuition on why certain problems are graph search representable but do not have an algebraic form (beyond mentioning molecular optimization as an example) as this seems to be the main motivation to use your package over classical optimization techniques.
• "or integer program" -> "or integer programs"?
• I don't understand why you mention "with well defined linear objective function and linear constraints": If linearity is important here, you could just write "integer linear programs". Otherwise, mentioning linearity does not support your argument that graph search problems are more expressive than classical representations.
• You use both a "traveling salesman problem" and "Traveling Salesman Problem" capitalization.
• You write "RLLib" while the associated paper writes it as "RLlib" in the title.

Statement of need

• JOSS asks for the target audience to be mentioned here.
• In the RLLib paragraph, it is not clear how the concepts of parametrically defined and invalid actions, flattening, masking, and successor state relate to what we learned in the summary. If these are central concepts, you should consider introducing them briefly in the summary. Otherwise this paragraph might be too technical for a statement of need.

[osorensen]

Thanks for your review @Viech!

Regarding scholarly scope, the guidelines state as some factors to consider, which I will consider point-by-point below, while trying to "think out loud".

• Age of software (is this a well-established software project) / length of commit history.

Looking at the repository, I find that the software seems rather young, with the first commit made on February 11 2022.

• Number of commits.

This is rather large, 241 in total.

• Number of authors.

There have been four contributors, which suggests that this is a joint effort.

• Total lines of code (LOC). Submissions under 1000 LOC will usually be flagged, those under 300 LOC will be desk rejected.

This one has already been commented on in @Viech's review.

• Whether the software has already been cited in academic papers.

Could you please comment on this @pstjohn? Is the software used in academic paper, or are you aware of papers in preparation which will use the package.

• Whether the software is sufficiently useful that it is likely to be cited by your peer group.

This is an important point. Making a joint wrapper around two existing libraries can in itself be very useful for users not familiar with those libraries.

In sum, I understand your concern about scholarly scope @Viech, and see that this is a difficult case. I would also be interested to hear what @iammix thinks of this, as the "Substantial scholarly effort" button has not been ticked off in your review checklist.

Also @Viech, could you think of any suggested extensions of the package that would make it more clearly within scope for JOSS?

You're of course also welcome to comment on this @pstjohn.

[idoby]

@osorensen Just adding a comment here since I did check the respective checkbox. Following the discussion here I went back and checked the commit history in greater depth and found that a large number of commits are just one-liners or seem to be purely about cosmetics/experimenting with settings.

So I would suggest the authors

• document these successful (or less successful) configurations and experiments to convince the reader that their library is indeed robust and stands for more than just integration between various libraries (which is great but personally not something I would read a journal to find out about), and
• go back and clean up some of the history so that important development milestones stand out more clearly.

Personally, I believe git history to be more than just a storage space for old versions of the code, it also serves to document the design and development process for a project, document decisions made, etc.

(also, apologies, this is my first review and I didn't realize reviews could extend beyond the checklist)

@pstjohn, as you see I've open three small issues in the source repository. When you have addressed these, and the four points points about release and archiving mentioned in my comment yesterday, I'm ready to go forward with acceptance.

[pstjohn]

Took a couple tries to get the .zenodo.json metadata in the right format, but I think I've made the requested paper edits and these associated tags:

• Make a tagged release of your software, and list the version tag of the archived version here.
  v0.1.3
• Archive the reviewed software in Zenodo or a similar service (e.g., figshare, an institutional repository)
• Check the archival deposit (e.g., in Zenodo) has the correct metadata. This includes the title (should match the paper title) and author list (make sure the list is correct and people who only made a small fix are not on it). You may also add the authors' ORCID.
• Please list the DOI of the archived version here.
