outputs separator statistics

Columns:

• RootCalls: The number of calls that happened at the root.
• FoundCuts: The total number of cuts generated by the separators. Note: Cutpool-FoundCuts \(= \sum_{i=1}^nsepas ( Foundcuts_i - DirectAdd_i )\).
• ViaPoolAdd: The total number of cuts added to the sepastore from the cutpool.
• DirectAdd: The total number of cuts added directly to the sepastore from the separator.
• Applied: The sum of all cuts from the separator that were applied to the LP.
• ViaPoolApp: The number of cuts that entered the sepastore from the cutpool that were applied to the LP.
• DirectApp: The number of cuts that entered the sepastore directly and were applied to the LP.

The number of cuts ViaPoolAdd + Directly should be equal to the number of cuts Filtered + Forced + Selected in the cutselector statistics.

Note

The following edge case may lead to over or undercounting of statistics: When SCIPapplyCutsProbing() is called, cuts are counted for the cut selection statistics, but not for the separator statistics. This happens, e.g., in the default plugin prop_obbt.c.

Precondition

This method can be called if SCIP is in one of the following stages:

• SCIP_STAGE_SOLVING
• SCIP_STAGE_SOLVED
