Description |
|
ISTAT_MODEL_STAT |
The model status, value taken from the ModelStatus enumeration. |
|
ISTAT_SOLVER_STAT |
The solver status, value taken from the SolverStatus enumeration. |
|
ISTAT_TOTAL_ITER |
The total number of iterations. |
|
ISTAT_NODES |
The number of MIP nodes. |
|
ISTAT_MEM_USED |
The total amount of memory used (in bytes). |
|
ISTAT_RESTART_OFF |
If 1, restart or update is not possible with current model. |
|
ISTAT_POSTSOLVE_WARN |
If 1, postsolve (if available) indicated that the solution found is not reliable. |
|
ISTAT_PRESOLVE_STAT |
If 1, AIMMS should try to obtain presolve status information from the solver by using the GetColumnData and GetRowData methods. |
|
ISTAT_POSTSOLVE_CONT |
Solver option setting for option 'postsolve continuous variables' (if available), used by AIMMS when doing postsolve. |
|
ISTAT_POSTSOLVE_INT |
Solver option setting for option 'postsolve integer variables' (if available), used by AIMMS when doing a (MIP) postsolve. |
|
ISTAT_MIP_CALC_SENS |
Solver option setting for option 'MIP calculate basis and marginals' (if available), used by AIMMS when doing a (MIP) postsolve. |
|
ISTAT_BRANCHES |
The number of CP branches. |
|
ISTAT_FAILURES |
The number of search failures (CP). |
|
ISTAT_CALC_FARKAS |
If 1, a Farkas infeasibility proof has been calculated. |
|
ISTAT_MAX |
Size of int_stat output argument of the DoSolve method. |
