Abstract
Abstract In this paper we propose a weighted upwinding finite volume method on a nonstandard covolume grid for the variable coefficient convection‐diffusion problems. We give a simple method of choosing the optimal weighted factors depending on the local Peclet's numbers of the original problem. With the optimal factors the method overcomes numerical oscillation and avoids the numerical dispersion and has high‐order computing accuracy. The conservation law and the maximum principle are proved. The second‐order error estimates in L 2 and discrete H 1 norms are obtained for the optimal weighted upwinding finite volume method. Numerical experiments are given to illustrate the performance of the method. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
