lang=EN-US style='font-size:9.0pt;font-family:Arial'>I am going to implement a
program which needs to add and delete constraints (rows) dynamically. It is
easy to add a constraint by invoking the addRows() member function of
OsiCpxSolverInterface. However, I don’t know exactly how to remove a
constraint. The only method to remove constraint through the
OsiCpxSolverInterface is to call the deleteRows(int num, int *rowIndices)
function, but the problem is that how to know the exact row index is, since the
order of rows may be vary after several add and delete operation. And also, how
to get the row index of the newly added row?</span></font></p>
