alpaqa::PGAParams

struct alpaqa::PGAParams

Collaboration diagram for PGAParams:

Class Members
LipschitzEstimateParams	Lipschitz	Parameters related to the Lipschitz constant estimate and step size.
unsigned	max_iter	Maximum number of inner iterations.
microseconds	max_time	Maximum duration.
real_t	L_min	Minimum Lipschitz constant estimate.
real_t	L_max	Maximum Lipschitz constant estimate.
PANOCStopCrit	stop_crit	What stop criterion to use.
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.
real_t	quadratic_upperbound_tolerance_factor
