Smoothing SQP methods for solving nonsmooth and nonconvex constrained optimization problems
Bibliographic record
Abstract
We consider an optimization problem with both the objective function and the constraint functions possibly nonsmooth and nonconvex. We use smoothing functions with the gradient consistency property to approximate the nonsmooth functions and in- troduce a robust sequential quadratic programming (SQP) algorithm. We show that any accumulation point of the iteration sequence generated by the smoothing SQP algorithm is a Clarke stationary point, provided that the sequence of multipliers and the sequence of exact penalty parameters are bounded. Furthermore, we propose a new condition called the weakly generalized Mangasarian Fromovitz constraint qualification (WGMFCQ) that is weaker than the GMFCQ. We show that the extended version of the WGMFCQ guar- antees the boundedness of the sequence of multipliers and the sequence of exact penalty parameters and thus guarantees the global convergence of the smoothing SQP algorithm. We demonstrate that the WGMFCQ can be satisfied by bilevel programs for which the GMFCQ never holds. Preliminary numerical experiments show that the algorithm is effi- cient for solving nonsmooth and nonconvex optimization problems, including the simple

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
