|
|
type
|

Example
The following example prints the current penalty factor of row 1:
XPRSalltype alltype;
XSLPgetrowinfo(prob, XSLP_ROWINFO_CURRENTPENALTYFACTOR, 1, &alltype);
printf("penaltyfactor[1]=%f\n", alltype.value.real);
Further information
1. If the data is not available, the type of the returned p_info is set to
XPRStype_undefined.
2. Please refer to the header file
xprs.h for the definition of XPRSalltype.
3. The following constants are provided for row information handling:
- XSLP_ROWINFO_SLACK
- Get the current slack value of the row
- XSLP_ROWINFO_DUAL
- Get the current dual multiplier of the row
- XSLP_ROWINFO_NUMPENALTYERRORS
- Get the number of times the penalty error vector has been active for the row
- XSLP_ROWINFO_MAXPENALTYERROR
- Get the maximum size of the penalty error vector activity for the row
- XSLP_ROWINFO_TOTALPENALTYERROR
- Get the total size of the penalty error vector activity for the row
- XSLP_ROWINFO_CURRENTPENALTYERROR
- Get the size of the penalty error vector activity in the current iteration for the row
- XSLP_ROWINFO_CURRENTPENALTYFACTOR
- Set the size of the penalty error factor for the current iteration for the row
- XSLP_ROWINFO_PENALTYCOLUMNPLUS
- Get the index of the positive penalty column for the row (+)
- XSLP_ROWINFO_PENALTYCOLUMNPLUSVALUE
- Get the value of the positive penalty column for the row (+)
- XSLP_ROWINFO_PENALTYCOLUMNPLUSDJ
- Get the reduced cost of the positive penalty column for the row (+)
- XSLP_ROWINFO_PENALTYCOLUMNMINUS
- Get the index of the negative penalty column for the row (-)
- XSLP_ROWINFO_PENALTYCOLUMNMINUSVALUE
- Get the value of the negative penalty column for the row (-)
- XSLP_ROWINFO_PENALTYCOLUMNMINUSDJ
- Get the reduced cost of the negative penalty column for the row (-)
4. This function can be used to get the current SLP iteration solution in the case where this is not available using
XSLPgetslpsol due to solution filtering via
XSLP_FILTER.
