Abstract

fetched live from OpenAlex

Given a point set S = R ∪ B , where R is a set of red points and B is a set of blue points, we desire to find T * , a minimum weight spanning tree such that every edge has one red endpoint and one blue endpoint and no two edges cross.We call T * a bichromatic plane minimum spanning tree (MinBPST).We say a point set is semi-collinear when the blue points lie on a line and the red points lie on one side of the line.In this thesis, we present an O(|B | 3 |R| 2 ) running time algorithm for finding T * on a set of semi-collinear points.We also discuss an implementation of this algorithm.Additionally, we describe changes that can be made to the algorithm presented to solve other related problems.Finally, we describe properties of T * on semi-collinear point sets.16 Illustration of Base Case 5 . . . . . . . . . . . . .

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
