creates a constraint handler

Parameters
conshdlrpointer to constraint handler data structure
setglobal SCIP settings
messagehdlrmessage handler
blkmemblock memory for parameter settings
namename of constraint handler
descdescription of constraint handler
sepaprioritypriority of the constraint handler for separation
enfoprioritypriority of the constraint handler for constraint enforcing
checkprioritypriority of the constraint handler for checking feasibility (and propagation)
sepafreqfrequency for separating cuts; zero means to separate only in the root node
propfreqfrequency for propagating domains; zero means only preprocessing propagation
eagerfreqfrequency for using all instead of only the useful constraints in separation, propagation and enforcement, -1 for no eager evaluations, 0 for first only
maxpreroundsmaximal number of presolving rounds the constraint handler participates in (-1: no limit)
delaysepashould separation method be delayed, if other separators found cuts?
delaypropshould propagation method be delayed, if other propagators found reductions?
needsconsshould the constraint handler be skipped, if no constraints are available?
proptimingpositions in the node solving loop where propagation method of constraint handlers should be executed
presoltimingtiming mask of the constraint handler's presolving method

)

increases age of constraint by 1.0; should be called

  • in constraint separation, if no cut was found for this constraint,
  • in constraint enforcing, if constraint was feasible, and
  • in constraint propagation, if no domain reduction was deduced; if it's age exceeds the constraint age limit, makes constraint obsolete or marks constraint to be made obsolete in next update
Parameters

SCIP_RETCODE SCIPconsResetAge ( SCIP_CONS cons,
SCIP_SET set 
)

resets age of constraint to zero; should be called

  • in constraint separation, if a cut was found for this constraint,
  • in constraint enforcing, if the constraint was violated, and
  • in constraint propagation, if a domain reduction was deduced; if it was obsolete, makes constraint useful again or marks constraint to be made useful again in next update
Parameters

SCIP_RETCODE SCIPconsPushProp ( SCIP_CONS cons)

adds an active constraint to the propagation queue(if not already marked for propagation) of corresponding constraint handler and marks the constraint to be propagated in the next propagation round

Note
if constraint is added to the queue it will be captured
Parameters
consconstraint

resolves the given conflicting bound, that was deduced by the given constraint, by putting all "reason" bounds leading to the deduction into the conflict queue with calls to SCIPaddConflictLb(), SCIPaddConflictUb(), SCIPaddConflictBd(), SCIPaddConflictRelaxedLb(), SCIPaddConflictRelaxedUb(), SCIPaddConflictRelaxedBd(), or SCIPaddConflictBinvar();

Parameters

inferinfouser inference information attached to the bound change
inferboundtypebound that was deduced (lower or upper bound)
bdchgidxbound change index, representing the point of time where change took place
