ISolverMathProgramInstance::GetIIS Method

Provides the irreducibly inconsistent set (IIS).

virtual _LONG_T GetIIS(
    _LONG_T no_rows, 
    _LONG_T * rownos, 
    _LONG_T no_cols, 
    _LONG_T * colnos
) = 0;

Parameters	Description
_LONG_T no_rows	The numbers of rows in the IIS
_LONG_T * rownos	Array of length no_rows in which the indices of the rows of the IIS should be filled in
_LONG_T no_cols	The numbers of columns in the IIS.
_LONG_T * colnos	Array of length no_cols in which the indices of the columns of the IIS should be filled in

In case the solver does not support IIS or in case of an error, the GetIIS method should return AOSI_FAILURE, otherwise AOSI_SUCCESS.

The GetIIS method is called by AIMMS to request a solver to place the irreducibly inconsistent set (IIS) in the buffers supplied by AIMMS.

Prior to calling GetIIS, AIMMS retrieves the number of rows and columns in the IIS via a call to the FindIIS method.
