NTuple{81,Cchar} bad_alloc

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

Int32 iter

the total number of iterations required

Int32 iter_pass2

the total number of pass-2 iterations required

T obj

the value of the quadratic function

T obj_regularized

T multiplier

the multiplier, \(\sigma \|x\|^{p-2}\)

T xpo_norm
