inform derived type as a Julia structure

components

INT status

return status. See DQP_solve for details

INT 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

INT iter

the total number of iterations required

INT cg_iter

the total number of iterations required

INT 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

INT nfacts

the total number of factorizations performed

INT threads

the number of threads used

T obj

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

T primal_infeasibility

the value of the primal infeasibility

T dual_infeasibility

the value of the dual infeasibility

T complementary_slackness

the value of the complementary slackness

T non_negligible_pivot

the smallest pivot that was not judged to be zero when detecting linearly dependent constraints

Bool feasible

is the returned “solution” feasible?

INT checkpointsIter[16]

checkpoints(i) records the iteration at which the criticality measures first fall below \(10^{-i-1}\), i = 0, …, 15 (-1 means not achieved)
