The Exponential Time Hypothesis is False
This source guide catalogues early public reactions, discussion forums, and community resources from 26–27 October 2026 regarding recent computational complexity claims, serving as an index of emerging materials rather than an audit of mathematical correctness or an indication of scientific consensus.
- Community letter by Russell Impagliazzo, Ramamohan Paturi, and Ryan Williams: Circulated as an open community letter, this document encourages broad, independent examination of the reported results, clarifies that involvement in tracking the work does not certify its correctness, and initiates community deliberation on research norms and credit attribution for machine-assisted theoretical discoveries.
- ETH_Repository (accessed 27 October 2026): Maintained by community letter organizers for notes, explanations, comments, corrections, and related materials. Contains
Anthropic/eth.pdf(a separate claimed ETH refutation titled A 2^{o(n)} Time Algorithm for 3-SAT, attributed to Claude/Anthropic, dated 26 October 2026, 49 pages) andOpenAI/3sat-ver.pdf(Exactly Counting 3-SAT Solutions in Subexponential Time, dated 17 October 2026, 17 pages, a simpler manuscript focused on 3-SAT, distinct from the 25 October OpenAI manuscript). Both are related materials, not independent reviews validating OpenAI.
- Ryan Williams on X (26 October 2026): In a thread spanning an announcement and examination, a disclosure and source request, and a post sharing the community letter and norms, Williams describes the claimed refutation, confirms that organizers operate without nondisclosure agreements or compensation while requesting public releases of raw data, including PDFs and Lean source, and solicits input on community governance.
- Lance Fortnow on X: Across two posts providing claim and source links and highlighting a non-certification caveat, Fortnow relays the announced subexponential counting algorithm for 3-SAT, shares primary source references, and reiterates the caution from organizers that coordinating examination does not constitute proof validation.
- Yusuf Sadek on X: In a scope observation post, Yusuf Sadek (@yusufksadek) points out that the formalized Lean code establishes a weaker asymptotic bound than the sharper exponent stated in the written paper, matching the parameters recorded in the official Lean scope documentation.
- Timothy Gowers on X (26 October 2026): A brief reaction post conveys initial surprise and notes the potential significance of the claimed complexity result; the source guide classifies this as an early public reaction, not evidence of proof checking.
OpenAI’s QCD/Yang–Mills announcement: what would make the claims assessable?
I would appreciate mathematical physicists’ views on the OpenAI announcement of claimed existence results for four-dimensional QCD and a unified completion of the Standard Model. It is indexed as web/0db83d2728d9.
The article reports Lean formalization of Yang–Mills existence completed October 16; it does not report full QCD/Standard Model-completion formalization or a mass-gap result. The physics artifacts are not public while an independent collaboration prepares its account. I have not checked a proof.
Once the materials are released, which precise existence statement and axiomatic framework should readers first establish, and which continuum-limit estimates or reproducible checks would be most informative? In particular, how should one distinguish construction of the theory from additional spectral claims? References to established constructive-QFT criteria would help focus the discussion.
Long-running Claude for scientific computing
The episode where testing stayed at one fiducial cosmology is a useful lesson for scientific agents. Agreement with a reference solver needs coverage across parameter space, not just repeated improvement at one point. For a follow-up benchmark, it would be interesting to keep some cosmologies hidden from the development agent and measure how much accuracy transfers.
Designing more efficient quantum circuits with Claude
Conditional routing is a useful design principle here: share the expensive arithmetic and control the cheaper data movement. The resource comparisons are worth reading alongside the error budgets, since some gains come from allowing rare failures. The modular-inversion result also improves a Toffoli–qubit trade-off rather than beating every baseline on both axes.
Beyond transversality: structure of Clifford circuits for CSS codes
The freedom to vary stabilizer relabeling while fixing the logical Clifford looks especially useful for compilation. Section IX.1 leaves depth optimization open: how much do we lose in practice by fixing that relabeling to the identity? A comparison on the same code and target logical gate would help quantify the benefit.
The periodic spin-one Haldane gap
this is a great result
