Solver settings

The solver settings are displayed in the following table. The settings marked with * can be changed without running the setup method again.

Argument	Description	Allowed values	Default value
rho *	ADMM rho step	0 < rho	0.1
sigma	ADMM sigma step	0 < sigma	1e-06
max_iter *	Maximum number of iterations	0 < max_iter (integer)	4000
eps_abs *	Absolute tolerance	0 <= eps_abs	1e-03
eps_rel *	Relative tolerance	0 <= eps_rel	1e-03
eps_prim_inf *	Primal infeasibility tolerance	0 <= eps_prim_inf	1e-04
eps_dual_inf *	Dual infeasibility tolerance	0 <= eps_dual_inf	1e-04
alpha *	ADMM overrelaxation parameter	0 < alpha < 2	1.6
linsys_solver	Linear systems solver type	See Linear Systems Solvers	qdldl
delta *	Polishing regularization parameter	0 < delta	1e-06
polish *	Perform polishing	True/False	False
polish_refine_iter *	Refinement iterations in polish	0 < polish_refine_iter (integer)	3
verbose *	Print output	True/False	True
scaled_termination *	Scaled termination conditions	True/False	False
check_termination *	Check termination interval	0 (disabled) or 0 < check_termination (integer)	25
warm_start *	Perform warm starting	True/False	True
scaling	Number of scaling iterations	0 (disabled) or 0 < scaling (integer)	10
adaptive_rho	Adaptive rho	True/False	True
adaptive_rho_interval	Adaptive rho interval	0 (automatic) or 0 < adaptive_rho_interval (integer)	0
adaptive_rho_tolerance	Tolerance for adapting rho	1 <= adaptive_rho_tolerance	5
adaptive_rho_fraction	Adaptive rho interval as fraction of setup time (auto mode)	0 < adaptive_rho_fraction	0.4
time_limit *	Run time limit in seconds	0 (disabled) or 0 <= time_limit	0

The boolean values True/False are defined as 1/0 in the C interfaces.
