prob
|
The current problem.
|
|
rowtype
|
The type of the row:
|
|
origcolind
|
Integer array of length
norigcoefs containing the column indices of the row to presolve.
|
|
origrowcoef
|
Double array of length
norigcoefs containing the non-zero coefficients of the row to presolve.
|
|
origrhs
|
The right-hand side constant of the row to presolve.
|
|
norigcoefs
|
Number of elements in the
origcolind and
origrowcoef arrays.
|
- ncoefs
- The number of elements in the colind and rowcoef arrays.
- colind
- The column indices of the presolved row
- rowcoef
- The coefficients of the presolved row
- rhs
- The presolved right-hand side.
- status
-
Status of the presolved row:
- -3
- Failed to presolve the row due to presolve dual reductions;
- -2
- Failed to presolve the row due to presolve duplicate column reductions;
- -1
- Failed to presolve the row due to an error. Check the Optimizer error code for the cause;
- 0
- The row was successfully presolved;
- 1
- The row was presolved, but may be relaxed.
