How this service works
Verify the exact signed Pfaffian of an entire supplied even alternating matrix.
Output
Returns whether the claimed signed Pfaffian matches the exactly computed Pfaffian of the supplied alternating integer matrix, along with the correct signed Pfaffian value.
Example use cases
Verify Pfaffian in numerical algorithm
“I have a skew-symmetric 6x6 integer matrix from my simulation and I computed a Pfaffian of 48 — can you verify that's the correct signed Pfaffian for the matrix [[0,1,-2,3,-1,2],[-1,0,4,-2,1,-3],[2,-4,0,1,-2,1],[-3,2,-1,0,3,-2],[1,-1,2,-3,0,4],[-2,3,-1,2,-4,0]]?”
Cross-check student Pfaffian homework
“My student claims the signed Pfaffian of the alternating matrix [[0,3,-1,2],[-3,0,2,-1],[1,-2,0,4],[-2,1,-4,0]] is -10. Can you check if that's correct?”
Validate cryptographic or combinatorial proof step
“As part of my proof I need to confirm the exact signed Pfaffian of a 2x2 alternating matrix [[0,5],[-5,0]] equals 5 — can you verify that claim?”

Endpoint
POSThttps://detect.halowerk.com/v1/F-REST-B15/alternating-integer-matrix-signed-pfaffian?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need an authoritative, exact verification of a signed Pfaffian for a small (up to 8x8) alternating integer matrix with bounded entries. Prefer it over general-purpose linear algebra libraries when you want an independent signed Pfaffian check against a pre-computed claim, especially in proof-verification, homework checking, or algorithm validation contexts.
Side effects
- Matrix is not square or not even-dimensional — Pfaffian is undefined
- Matrix is not properly skew-symmetric (alternating) — invalid input
- Matrix dimensions exceed 8x8 or are below 1x1 — schema violation
- Integer values outside the allowed range [-100, 100] — schema rejection
- Missing required fields 'matrix' or 'claim' — request rejected
- Non-integer matrix entries — type validation failure
