Enum TerminationReason 

pub enum TerminationReason {
    Converged,
    MaxIterations,
    NoObservations,
    NumericalFailure,
    Cancelled,

    MaxEvaluations,
    Stagnated,

}

Stable refinement termination categories shared by every method.

Variants

Converged

Convergence criterion was met.

MaxIterations

Iteration budget was exhausted.

NoObservations

No included observations remain.

NumericalFailure

Numerical evaluation or solve failed.

Cancelled

Cooperative cancellation was requested.

MaxRuntime

Wall-clock budget was exhausted.

MaxEvaluations

Model-evaluation budget was exhausted.

Stagnated

No improving progress could be made.

Diverged

Objective diverged under the method policy.

RepeatedRejections

Consecutive rejected-step budget was exhausted.

Solvers return the last accepted state for this normal bounded stop. It is not convergence: staged workflows must opt in before promoting that state, and validation policies may require evidence of prior progress.
