SolvSRK for Real-Time Uncertainty Quantification

A flight control law is being certified. Regulators ask, plausibly, “how confident are you that this law works across the envelope of real flight conditions?” The team’s answer today is a Monte Carlo campaign. Twenty thousand simulation runs. A data center for a weekend. Budget line: $100K just in compute. A hundred engineering hours to orchestrate. Regulators ask the same question again next quarter.

Imagine a solver that delivers calibrated error bars on a single run. The regulator gets a rigorous answer, the team gets a Friday afternoon back, the compute bill drops two orders of magnitude. Certification becomes a routine query instead of a campaign.

A pharmacokinetic model is used at a hospital to dose a narrow-therapeutic-index drug. Uncertainty matters: overshoot risks toxicity, undershoot risks therapeutic failure. Today, clinicians run point estimates and apply a standard safety multiplier. Nobody knows if that multiplier is right for this patient.

Uncertainty quantification from a single solve — fast enough to run at the bedside — gives a per-patient confidence interval on the dose. The safety multiplier becomes patient-specific. The standard of care shifts.

A bank runs a portfolio valuation at midnight, including an uncertainty estimate. The job is a massive Monte Carlo sweep. It is supposed to finish by 6 AM so traders have the risk numbers before the opening bell. Tonight, it is still running at 7:30 AM. Trading opens without it.

UQ from a single solve, vectorized across instruments, turns that batch from hours to minutes. The opening bell is no longer a race.
