Abstract
In this thesis, we consider several combinatorial optimization problems which feature assignment decisions. The first part deals with variants of the generalized assignment problem. We study an extension with additional minimum quantity constraints, and a generalization where the hard capacity constraints are relaxed by adding a convex summand to the objective function. Furthermore, we analyze a version of the separable assignment problem where it is allowed to assign items to multiple bins. For all these problems, we present results on their computational complexity and provide approximation algorithms that use randomized rounding based on configuration integer programming formulations. In the second part, we study an online version of the interval scheduling problem, where an upper bound on the number of failing intervals is known in advance, from the viewpoint of competitive analysis. A similar online setting is given in the Canadian traveler problem, an online variant of the shortest-path problem. For this problem we present a randomized online algorithm and prove that it is best-possible on node-disjoint paths.

How this classification was reachedexpand
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.
