copy method for node selector plugins (called when SCIP copies plugins)
input:
Definition at line 47 of file type_nodesel.h.
#define SCIP_DECL_NODESELFREE | ( | x | ) | SCIP_RETCODE x (SCIP* scip, SCIP_NODESEL* nodesel) |
destructor of node selector to free user data (called when SCIP is exiting)
input:
Definition at line 56 of file type_nodesel.h.
#define SCIP_DECL_NODESELINIT | ( | x | ) | SCIP_RETCODE x (SCIP* scip, SCIP_NODESEL* nodesel) |
initialization method of node selector (called after problem was transformed)
input:
Definition at line 64 of file type_nodesel.h.
#define SCIP_DECL_NODESELEXIT | ( | x | ) | SCIP_RETCODE x (SCIP* scip, SCIP_NODESEL* nodesel) |
deinitialization method of node selector (called before transformed problem is freed)
input:
Definition at line 72 of file type_nodesel.h.
#define SCIP_DECL_NODESELINITSOL | ( | x | ) | SCIP_RETCODE x (SCIP* scip, SCIP_NODESEL* nodesel) |
solving process initialization method of node selector (called when branch and bound process is about to begin)
This method is called when the presolving was finished and the branch and bound process is about to begin. The node selector may use this call to initialize its branch and bound specific data.
input:
Definition at line 83 of file type_nodesel.h.
#define SCIP_DECL_NODESELEXITSOL | ( | x | ) | SCIP_RETCODE x (SCIP* scip, SCIP_NODESEL* nodesel) |
solving process deinitialization method of node selector (called before branch and bound process data is freed)
This method is called before the branch and bound process is freed. The node selector should use this call to clean up its branch and bound data.
input:
Definition at line 94 of file type_nodesel.h.
#define SCIP_DECL_NODESELSELECT | ( | x | ) | SCIP_RETCODE x (SCIP* scip, SCIP_NODESEL* nodesel, SCIP_NODE** selnode) |
node selection method of node selector
This method is called to select the next leaf of the branch and bound tree to be processed.
input:

#define SCIP_DECL_NODESELCOMP | ( | x | ) | int x (SCIP* scip, SCIP_NODESEL* nodesel, SCIP_NODE* node1, SCIP_NODE* node2) |
node comparison method of node selector
This method is called to compare two nodes regarding their order in the node priority queue.
