# AddCut(Int32, Inequality.Definition) Method

Add a cut at the current node. It is assumed that the left-hand Side ( lhs) is formulated in terms of the original model. So you can use Variable instances to formulate it. When using plain variable indices, be sure these indices are for the original model. The function will automatically Transform (presolve) the cut to the presolved space. If presolving the cut fails then the cut is not added and the reason for failure is returned. Failing to Presolve (and thus adding) a cut is not a problem in every context. That is why this does not raise an exception but instead leaves it to the caller to decide whether this is an error or not.
