inform derived type as a C struct

components

ipc_ status

return status. See CLLS_solve for details.

ipc_ alloc_status

the status of the last attempted allocation/deallocation.

char bad_alloc[81]

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

ipc_ iter

the total number of iterations required

ipc_ factorization_status

the return status from the factorization

int64_t factorization_integer

the total integer workspace required for the factorization

int64_t factorization_real

the total real workspace required for the factorization

ipc_ nfacts

the total number of factorizations performed

ipc_ nbacts

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

ipc_ threads

the number of threads used

rpc_ obj

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

rpc_ primal_infeasibility

the value of the primal infeasibility

rpc_ dual_infeasibility

the value of the dual infeasibility

rpc_ complementary_slackness

the value of the complementary slackness

rpc_ 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?

ipc_ 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)

rpc_ checkpointsTime[16]

see checkpointsIter
