Abstract

fetched live from OpenAlex

It is often important to know more about the characteristics of a mathematical program than the simple information that is returned by a solver. For example, to choose an appropriate solution algorithm, one may need to know something about the convexity of the functions in a nonlinear program, or about which constraints are redundant. For the complex model forms, particularly nonlinear programs and mixed-integer programs, random sampling can discover a great deal of information. This paper describes how to discover interesting characteristics of mathematical programs via sampling, and describes solutions to several difficulties that arise in practice. Several new techniques for discovering characteristics and for improving the accuracy of the characterizations are described.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
