Options:

——-

initial_tr_radiusfloat

Initial trust-region radius.

max_tr_radiusfloat

Maximum value of the trust-region radius. No steps that are longer than this value will be proposed.

etafloat

Trust region related acceptance stringency for proposed steps.

gtolfloat

Gradient norm must be less than gtol before successful termination.
