COUNTING FUNCTIONS OF MAGIC LABELLINGS
Bibliographic record
Abstract
A magic labelling of a set system is a labelling of its points by distinct positive integers so that every set of the system has the same sum, the magic sum. The most famous class of examples are magic squares (the sets are the rows, columns, and diagonals of a matrix). It follows from a recent paper by Matthias Beck and Thomas Zaslavky that the number of n by n magic labellings is a quasipolynomial function of the magic sum, and also of an upper bound on the entries in the square. The contribution of this thesis is to develop software that allows computation of a large class of examples of generating functions for such counting functions. The software will utilize previously developed programs THAC (developed at SFSU) and Latte (developed at UC Davis) to compute intermediate results required by the overall computation. The symbolic algebra program Maple (developed at the University of Waterloo, Canada) will be used for final algebraic manipulation to achieve the final result which is the generating function of a counting function. While there are other methods to compute these types of counting functions, it is believed that the approach used in this thesis is novel and no such software exists.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
