Abstract

fetched live from OpenAlex

In this thesis we will analyse the two algorithms for linear programming (LP) presented by Stojkovic and Stanimirovic [15] in 2001. One of the methods, which the authors call the "minimal angles method" (MA method) was designed to determine either an optimal extreme point or an extreme point adjacent to an optimal extreme point. Unfortunately, the theorem upon which the MA method is based is not valid. This was shown by Li [10] in 2004 with two counterexamples. We will show that one of the counterexamples itself is not valid, and will provide an alternate, valid counterexample. We will also provide a careful study of the MA method to see if there is a class of LP, where it can be applied. This leads to a method we call the "active cone method" which can be used for 2 variable LPs. The second method of Stojkovic and Stanimirovic [15] in 2001 uses an analogy to Game Theory to devise a process, based on "dominated strategies", to simplify a certain class of LP. We extend this idea and present an iterative method which provides further reduction to a large class of LPs.Dept. of Mathematics and Statistics.

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.
