Wikipedia:Articles for deletion/Polynomial transformations
per . This is an encyclopedic topic (one that is completely unrelated to the proposed redirect target polynomial-time reduction despite the similarity of name) and Deltahedron has improved it to the point where it looks like an encyclopedia article. It still could use more improvement (especially inline sources) but that's not a big enough problem to warrant deletion
