[Osi] modify constraint system

[Arno Schödl]

Hello,

 

I use OSI with Clp (and may try Dylp later). In my application, I need to modify the constraint system, in particular iterating over

 

- for a particular column, zero out some row entries, 

- change the bounds of these same rows, 

- and then resolve.

 

>From the OsiSolverInterface doc, I could not figure out how to do that. Is it supported at all, or do I need to remove the row and add it back with different coefficients?

 

Thank you for help,

 

Arno
