BCP_branching_result
This enumerative constant describes the possible outcomes of a branching attempt.
@ BCP_BranchingDivedIntoNewNode
Branching happened, one of the children is kept and that's what the LP process will continue to work ...
@ BCP_BranchingContinueThisNode
No branching happend, continue to work on the same node.
@ BCP_BranchingFathomedThisNode
The node is fathomed, the LP process should wait for a new node.
BCP_child_action
This enumerative constant describes the possible values the set_actions_for_children() method of \URL...
@ BCP_ReturnChild
This child should be returned to the Tree Manager for later processing.
@ BCP_FathomChild
This child should be fathomed.
@ BCP_KeepChild
This child should be kept and dived into (provided diving is decided on.
BCP_diving_status
This enumerative constant describes the diving status of the search tree node processed by the LP pro...
@ BCP_DoDive
After branching the LP process is free to decide whether it keeps a child to dive into.
@ BCP_DoNotDive
After branching all children must be returned to the Tree Manager and the LP process should wait for ...
@ BCP_TestBeforeDive
After branching the LP process must inquire of the Tree Manager whether it can dive into one of the c...
@ BCP_UnknownDivingStatus
Nonexistent diving status.

BCP_branching_decision
This enumerative constant is the return value of the select_branching_candidates() method in \URL[BCP...
@ BCP_DoBranch
Branching must be done.
@ BCP_DoNotBranch_Fathomed
The node should be fathomed without even trying to branch.
@ BCP_DoNotBranch
BCP should continue to work on this node.
BCP_branching_object_relation
This enumerative constant is the return value of the compare_presolved_branching_objects() method in ...
@ BCP_OldPresolvedIsBetter
"old" is better, discard "new".
@ BCP_NewPresolvedIsBetter_BranchOnIt
"new" is better and it's so good that even if there are more candidates forget them and use "new" as ...
@ BCP_NewPresolvedIsBetter
"new" is better, discard "old".
BCP_child_preference
This enumerative constant describes which child should be kept after the branching object is selected...
@ BCP_PreferChild_LowBound
Keep the child that has the lowest presolved objective value.
@ BCP_PreferChild_HighBound
Keep the child that has the highest presolved objective value.
@ BCP_PreferDiveUp
Mainly for binary choices: take the up branch unconditionally.
@ BCP_PreferChild_LessFractional
Keep the child that has the least to-be-integer variables at fractional level after presolving.
@ BCP_PreferChild_MoreFractional
Keep the child that has the most to-be-integer variables at fractional level after presolving.
@ BCP_PreferDiveDown
Mainly for binary choices: take the down branch unconditionally.
