Abstract

fetched live from OpenAlex

In open pit mining, one must dig a pit, that is, excavate the upperlayers of ground before reaching the ore. The walls of the pit must satisfysome mechanical constraints, in order not to collapse. The question thenarises how to mine the ore optimally, that is, how to Önd the optimalpit. We set up the problem in a continuous (as opposed to discrete)framework, and we show, under weak assumptions, the existence of anoptimum pit. For this, we formulate an optimal transportation problem,where the criterion is lower semi-continuous and is allowed to take thevalue+1. We show that this transportation problem is a strong dualto the optimum pit problem, and also yields optimality (complementarityslackness) conditions.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
