What the math gives to ML
The paper develops a Lagrangian decomposition that converts coupled sequential allocation into independent resource decisions while providing a pointwise optimistic upper bound for every nonnegative price vector. This structure transfers naturally to capacity-constrained neural routing, especially mixture-of-experts systems, where expert capacity is a shared constraint and router logits are token utilities. The paper also identifies a fluid complementary-slackness degeneracy: immediate utility, shadow rent, and continuation-value gradient can cancel exactly at the decision boundary. A practical neural adaptation is therefore to combine dual prices with explicit decision margins, making routing less sensitive to noise, quantization, and small state-estimation errors.

Replace a capacity-penalty-only MoE router with a nonnegative shadow price for each expert, capacity bucket, or hardware resource. Route each token using predicted utility minus the relevant price, while computing a decomposed optimistic objective that certifies how much utility remains above the feasible routed value.

Add a continuation-value correction and an explicit positive margin to routing or adaptive-computation decisions that consume a stateful resource. The margin prevents the degeneracy in which learned rent exactly cancels immediate surplus, making the network highly sensitive to noise, quantization, or small state-estimation errors.
