presol_dualagg.h File Reference Detailed Descriptionaggregate variables by dual arguments This presolver looks for variables which could not be handled by duality fixing because of one up-/downlock. If the constraint which delivers the up-/downlock has a specific structure, we can aggregate the corresponding variable. In more detail (for a minimization problem and the case of only one uplock): Given a variable with and only one up lock (originating from a constraint c), we are looking for a binary variable such that:
Similar arguments apply for the case of only one down lock and . Definition in file presol_dualagg.h. #include "scip/scip.h" Go to the source code of this file.
