inform derived type as a Julia structure

components

Int32 status

return status. See QPB_solve for details

Int32 alloc_status

the status of the last attempted allocation/deallocation

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 cg_iter

the total number of conjugate gradient iterations required

Int32 factorization_status

the return status from the factorization

Int64 factorization_integer

the total integer workspace required for the factorization

Int64 factorization_real

the total real workspace required for the factorization

Int32 nfacts

the total number of factorizations performed

Int32 nbacts

the total number of “wasted” function evaluations during the linesearch

Int32 nmods

the total number of factorizations which were modified to ensure that th matrix was an appropriate preconditioner

T obj

the value of the objective function at the best estimate of the solution determined by QPB_solve

T non_negligible_pivot

the smallest pivot which was not judged to be zero when detecting linear dependent constraints

Bool feasible

is the returned “solution” feasible?
