}Expand description
Termination tolerances passed through to NLopt’s nlopt_stopping.
Fields§
§stopval: f64Stop when objective drops at or below stopval. Disabled if
non-positive (mapped to -INFINITY internally). The upstream
cobyla crate’s minimize() hardcoded this to -INFINITY —
re-exposing it as a tuning knob.
ftol_abs: f64Stop when |Δf| < ftol_abs. Disabled if non-positive.
ftol_rel: f64Stop when |Δf|/|f| < ftol_rel. Disabled if non-positive.
xtol_abs: f64Stop when ||Δx||_inf < xtol_abs. Disabled if non-positive.
xtol_rel: f64Stop when ||Δx||/||x|| < xtol_rel. Disabled if non-positive.
