PROC OPTQP Macro Variable |
The OPTQP procedure defines a macro variable named _OROPTQP_. This variable contains a character string that indicates the status of the procedure. The various terms of the variable are interpreted as follows.
indicates the solver status at termination. It can take one of the following values:
The procedure terminated normally.
Incorrect syntax was used.
The input data were inconsistent.
Insufficient memory was allocated to the procedure.
A problem occurred in reading or writing data.
The status cannot be classified into any of the preceding categories.
indicates the solution status at termination. It can take one of the following values:
The solution is optimal.
The optimality of the solution cannot be proven.
The problem is infeasible.
The problem is unbounded.
The problem is infeasible or unbounded.
The maximum allowable number of iterations was reached.
The maximum time limit was reached.
The solver failed to converge, possibly due to numerical issues.
The quadratic matrix is nonconvex (minimization).
The quadratic matrix is nonconcave (maximization).
indicates the objective value obtained by the solver at termination.
indicates the (relative) infeasibility of the primal constraints at the solution. See the section Interior Point Algorithm: Overview for details.
indicates the (relative) infeasibility of the dual constraints at the solution. See the section Interior Point Algorithm: Overview for details.
indicates the (relative) violation by the solution of the lower or upper bounds (or both). See the section Interior Point Algorithm: Overview for details.
indicates the (relative) duality gap. See the section Interior Point Algorithm: Overview for details.
indicates the (absolute) complementarity at the optimal solution. See the section Interior Point Algorithm: Overview for details.
indicates the number of iterations required to solve the problem.
indicates the time taken for preprocessing (seconds).
indicates the time (in seconds) taken to solve the problem, including preprocessing time.
