pa::PANOCParams

struct pa::PANOCParams

Collaboration diagram for PANOCParams:

Class Members
LipschitzEstimateParams	Lipschitz	Parameters related to the Lipschitz constant estimate and step size.
unsigned	max_iter	Maximum number of inner PANOC iterations.
microseconds	max_time	Maximum duration.
real_t	τ_min	Minimum weight factor between Newton step and projected gradient step.
real_t	L_min	Minimum Lipschitz constant estimate.
real_t	L_max	Maximum Lipschitz constant estimate.
PANOCStopCrit	stop_crit	What stopping criterion to use.
unsigned	max_no_progress	Maximum number of iterations without any progress before giving up.
unsigned	print_interval	When to print progress. If set to zero, nothing will be printed. If set to N != 0, progress is printed every N iterations.
