Hi,
I'm using CLP to generate cutting planes for a function which is the minimum
of a linear program with varying right hand side.
I noticed that there are methods getReducedGradient and setObjectiveAndRefresh
in OsiClpSolverInterface to check whether a primal solution (basis) is still
optimal after a change of the objective function.
Similarly, I would like to know, if it is possible to check whether a dual
solution is still optimal after a change of the right-hand-side of the primal
problem.
Thanks a lot,
Stefan
