Abstract
Bipartite queueing networks with unknown statistics, where jobs are routed to and queued at servers and yield job-type and server-dependent utilities upon completion, model a wide range of problems in communications and related research areas (e.g., call routing in call centers, task assignment in crowdsourcing, job dispatching to cloud servers). Additionally, many such problems have additional routing constraints, such as quality of service or budgeted server cost constraints. The utility maximization problem in a bipartite queueing network with unknown statistics and subject to additional routing constraints is a constrained bandit learning problem with delayed feedback that depends on the server queueing delay. In this paper, we propose an efficient algorithm that overcomes the technical shortcomings of the state-of-the-art and effectively balances utility regret and peak job completion delay, while achieving constant peak constraint violation for the additional sample path routing constraints. Empirically, our algorithm is shown to simultaneously achieve low regret, peak delay, and peak constraint violation compared to existing algorithms.

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
