The precise statements and locators cited in this P versus NP research record.
Source-reported preprint/project; independent mathematical assessment pending.
The exact passages cited in OpenMath. Each passage identifies how its wording was recorded.
For every fixed ν, all-pairs shortest paths on directed n-vertex graphs with integer edge weights of absolute value at most n^ν and no negative cycles can be computed deterministically in O(n^{2.9995}) time.

The authors credit an internal Anthropic Claude model with algorithm discovery and later Lean formalization. They describe their simplification, strengthening, extensions and mathematical responsibility.
OpenMath source records preserve exact citations. Observation dates order these records; they do not establish the latest upstream paper or proof.
