Member Data Documentation

◆ current_node_id

int64_t operations_research::GScipCallbackStats::current_node_id = 0

A unique id within a run, assigned consecutively by order of creation. -1 if no nodes have been created yet, or num_processed_nodes if search is over. See SCIPgetCurrentNode().

Definition at line 135 of file gscip_constraint_handler.h.

◆ dual_bound

double operations_research::GScipCallbackStats::dual_bound = 0.0

The global dual bound on the problem. See SCIPgetDualBound().

Definition at line 153 of file gscip_constraint_handler.h.

◆ dual_simplex_iterations

int64_t operations_research::GScipCallbackStats::dual_simplex_iterations = 0

The number of pivots taken by the dual simplex method. See SCIPgetNDualLPIterations().

Definition at line 161 of file gscip_constraint_handler.h.

◆ num_cuts_in_lp

int32_t operations_research::GScipCallbackStats::num_cuts_in_lp = 0

The number of rows in the current LP that were added as cuts. See SCIPgetNPoolCuts().

Definition at line 169 of file gscip_constraint_handler.h.

◆ num_nodes_left

int64_t operations_research::GScipCallbackStats::num_nodes_left = 0

The number of open nodes left in the current run. See SCIPgetNNodesLeft().

Definition at line 142 of file gscip_constraint_handler.h.

◆ num_processed_nodes

int64_t operations_research::GScipCallbackStats::num_processed_nodes = 0

The number of processed nodes in the current run (i.e. does not include nodes before a restart), including the focus node. See SCIPgetNNodes().

Definition at line 139 of file gscip_constraint_handler.h.

◆ num_processed_nodes_total

int64_t operations_research::GScipCallbackStats::num_processed_nodes_total = 0

The total number of processed nodes in all runs, including the focus node. If the solver restarts > 1 time, will be larger than num_processed_nodes, otherwise is equal. See SCIPgetNTotalNodes().
