Overview

The precise statements and locators cited in this P versus NP research record.

Author full version dated March 2014; an extended abstract appeared at CCC 2012. The paper explicitly uses a bounded-error randomized formulation of SETH.

Passages

The exact passages cited in OpenMath. Each passage identifies how its wording was recorded.

§1 definition; Theorem 1.1(i); immediate consequence using deterministic algorithms as a subclass

If the stated bounded-error randomized SETH holds, then P ≠ NP.

Passage 2 · OpenMath paraphrasePermalink

§1, Previous Work, p. 1; Theorem 1.1(i)

For every fixed α in (0,1), there is a fixed clause width k such that k-CNF-SAT on n variables has no bounded-error randomized O(2^{αn})-time algorithm.

Explicit citations in versioned problem publications. A citation records a use; it does not confer proof or independent verification.

Source assessment

Proved

Established implication or scoped theorem in cited mathematics

Only a sufficient stronger premise; P ≠ NP gives no such exponent or randomized lower bound.

Observed Oct 10, 2026

Connection

The cited randomized SETH excludes even fixed-base exponential improvements for some clause width, and therefore excludes polynomial deterministic algorithms.

Strong Exponential Time Hypothesis — randomized version →

Source assessment

Open

Unresolved assertion in the cited scope

A fine-grained hardness premise stronger than the deterministic version; neither version follows from P ≠ NP.
