SCIP_RowSolVals Struct Reference

collected values of a row which depend on the LP solution We store these values in each row to recover the LP solution at start of diving or probing mode, say, without having to resolve the LP. We do not store the dualfarkas value since we expect a node with infeasible LP to be pruned anyway. In this unlikely case, we have to resolve the LP.
