inform derived type as a Julia structure

components

Int32 status

return status. See DGO_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 performed

Int32 f_eval

the total number of evaluations of the objective function

Int32 g_eval

the total number of evaluations of the gradient of the objective function

Int32 h_eval

the total number of evaluations of the Hessian of the objective function

T obj

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

T norm_pg

the norm of the projected gradient of the objective function at the best estimate of the solution determined by DGO_solve

T length_ratio

the ratio of the final to the initial box lengths

T f_gap

the gap between the best objective value found and the lowest bound

char why_stop[2]

why did the iteration stop? This wil be ‘D’ if the box length is small enough, ‘F’ if the objective gap is small enough, and ‘ ‘ otherwise
