  • 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.
