Abstract
We study the optical signal-to-noise ratio (OSNR) optimization problem in optical wavelength-division multiplexed (WDM) networks. This work extends our previous results in [1] on games with coupled constraints in optical links to generic WDM networks. We first develop a model for the network and an OSNR model for each link by investigating the interaction between the network and physical layers. The nonlinear threshold is considered as the link capacity constraint and we study the case in which channel powers are adjustable at the switching nodes. We formulate an OSNR Nash game with coupled utilities and constraints. Each player (channel) in the game maximizes its own utility function which is related to minimizing the individual OSNR degradation. We exploit this OSNR Nash game in two typical network topologies: multi-link topology and quasi-ring topology. The hierarchical decomposition approach leads to a lower-level game for channels with no coupled constraints and a higher-level optimization problem for the network.

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
