◆ SCIPprintSeparatorStatistics()

void SCIPprintSeparatorStatistics	(	SCIP *	scip,
		FILE *	file )

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.

- locks_down: Number of locks in the down direction.
- locks_up: Number of locks in the up direction.
- avg_depth: Average branching depth for the variable.
- branchings_down: Number of branchings in the down direction.
- branchings_up: Number of branchings in the up direction.
- strong_branchings: Number of strong branchings performed on the variable.
- avg_inferences_down: Average number of inferences per branching in the down direction.
- avg_inferences_up: Average number of inferences per branching in the up direction.
- cutoff_rate_down: Percentage of branchings in the down direction that led to cutoffs.
- cutoff_rate_up: Percentage of branchings in the up direction that led to cutoffs.
- pseudocost_down: Pseudocost in the down direction.
- pseudocost_up: Pseudocost in the up direction.
- pseudocost_count_down: Number of pseudocost updates in the down direction.
- pseudocost_count_up: Number of pseudocost updates in the up direction.
- pseudocost_variance_down: Variance of pseudocost in the down direction.
- pseudocost_variance_up: Variance of pseudocost in the up direction.
total_branchings_down: Total number of branchings in the down direction across all variables.
total_branchings_up: Total number of branchings in the up direction across all variables.
total_strong_branchings: Total number of strong branchings across all variables.
avg_inferences_down: Average inferences per branching in the down direction across all variables.
avg_inferences_up: Average inferences per branching in the up direction across all variables.
avg_cutoff_rate_down: Average cutoff rate for branchings in the down direction across all variables.
