How an LM run ended.

Variants

Converged

The iterate passed the FeasibilityTest.

IterationLimit

Iteration cap reached first.

Stationary

The projected gradient of ½‖c‖² vanished at a point that is not a root: a stationary point of the least-squares problem on the box (MINPACK’s gtol test, at STATIONARITY_TOL). No step this method can take leaves it, so it stops rather than collapse Δ to get there.

TrustRegionCollapsed

Δ collapsed: a projected stationary point of ‖c‖² that is not a root, as far as this method can tell.

EvaluationFailed

The residual or Jacobian could not be evaluated at an accepted point, or was not finite there.

LinearSolverFailed

The augmented system could not be factored at any λ tried.

CpuTimeExceeded

max_cpu_time ran out before the iterate passed the test.

WallTimeExceeded

max_wall_time ran out before the iterate passed the test.

UserRequestedStop

The TNLP’s intermediate_callback returned false.
