PowerWorld is committed to supporting the essential work done by our customers; our support staff is available for any queries. what happens if the objective coefficient at c2 (which initially is 0, because c2 is an auxiliary variable) starts changing in both direction. I mean sensitivity analysis with respect to the cost function and constraints. If programming with GLPK, bear in mind that the solver, paradoxically perhaps, need not have found a solution to return success it only needs to have completed its assigned tasks satisfactorily.
