TACAS Review Process

Model the pipeline before interpreting any single review. TACAS's process has three features that surprise authors arriving from other venues: reviewing is blind by category, the decision for a tool paper depends on a parallel artifact evaluation, and the whole thing runs in a single annual round on the ETAPS schedule with a short rebuttal — not a rolling or multi-round journal cycle.

Process model

• Submission and review run on EasyChair under the ETAPS joint schedule. Reviewing is per-category: regular research papers are double-blind; case-study, regular tool, and tool-demonstration papers are single-blind.
• Each paper is read by multiple PC members who weigh, for a research paper, the soundness and significance of the algorithm; for a tool paper, the tool's contribution and its working artifact; for a case study, the realism of the system and the honesty of the lessons.
• For regular tool and tool-demonstration papers, a mandatory artifact is evaluated by the Artifact Evaluation Committee in parallel with the PC, and the artifact outcome feeds the acceptance decision — a paper whose artifact does not work is in real jeopardy.
• There is a short rebuttal / author-response window before the PC finalizes decisions.
• Accepted papers publish in Springer LNCS, gold open access; badges earned by the AEC (Available / Functional / Reusable) are printed on the title page.

Reading a decision against the category

The strategic reading: for a tool paper, the artifact is part of the review — a great write-up with a broken package still fails. Budget the artifact like a co-equal deliverable, not an afterthought.

How TACAS differs from its siblings

• vs. CAV: CAV is the broader formal-methods flagship with more theory room and a different calendar; TACAS's identity is the tools-and-algorithms emphasis, the four categories, and the mandatory tool-paper artifact integrated into acceptance. Never assume a shared deadline, page limit, or template — TACAS is LNCS via ETAPS.
• vs. a journal (STTT/FMSD): a journal offers revise-and-resubmit and no page ceiling; TACAS is a single-round conference with a rebuttal, not an R&R. Route a long, proof-heavy treatment to the journal.
• vs. SV-COMP: the competition ranks verifiers on a common task set and its results are reported separately; a tool paper is peer-reviewed prose about a tool, judged on contribution and artifact, not on a leaderboard position.

Who reads you

Expect verification experts matched to your subarea. For a research paper they will check the soundness argument line by line; for a tool paper they (or the AEC) will try to run your artifact and reproduce a headline result; for a case study they will probe whether the system is representative. Vague algorithm descriptions and unreproducible tool claims are caught, not skimmed.

Where author leverage actually exists

[Before submission]  category choice + topic keywords -> reviewer match      (largest lever)
[Artifact (tool)]    a clean-VM package that reproduces the claims           (co-decides tool papers)
[Rebuttal]           correct factual misreadings, supply a requested number, clarify a proof step
[After reject]       no appeal; reroute to CAV/VMCAI/FMCAD or a journal, or return next TACAS cycle

A rebuttal moves borderline papers when it fixes a misreading or answers a concrete question; it does not move papers by arguing taste, and it cannot repair a fundamentally broken artifact after the fact.

Misreadings to avoid

• Thinking the artifact is post-acceptance for a tool paper — it is mandatory, parallel, and decision-feeding.
• Anonymity confusion — only research papers are double-blind; do not anonymize a single-blind tool paper, and do not deanonymize a research paper.
• Treating the rebuttal as a second submission — it is short and targeted; the paper as submitted carries the argument.
• Projecting CAV's or last year's process — categories, dates, and artifact rules are set per ETAPS edition.

Output format

[Process stage] pre-submission / under review / rebuttal / notified / accepted
[Category + blind mode] research (double-blind) / case-study|tool|tool-demo (single-blind)
[Decision drivers] soundness | tool+artifact | case realism | demo reproducibility
[Artifact status] (tool/tool-demo) reproduces claims on clean VM? yes/no
[Leverage plan] the next-stage action that can actually change the outcome
[Forbidden moves] wrong-category anonymity error / unrunnable artifact / unsupported new claims in rebuttal
