the name of the array for which an allocation/deallocation error occurred

INT iter

the total number of iterations required

INT iter_pass2

the total number of pass-2 iterations required

INT biters

the total number of inner iterations performed

INT biter_min

the smallest number of inner iterations performed during an outer iteration

INT biter_max

the largest number of inner iterations performed during an outer iteration

T obj

the value of the objective function

T multiplier

the multiplier, \(\lambda = \mu + \sigma \|x\|^{p-2} * \sqrt{\|Ax-b\|^2 + \mu \|x\|^2}\)

T x_norm

the Euclidean norm of \(x\)

T r_norm

the Euclidean norm of \(Ax-b\)
