creates a constraint handler

Parameters

conshdlr	pointer to constraint handler data structure
set	global SCIP settings
messagehdlr	message handler
blkmem	block memory for parameter settings
name	name of constraint handler
desc	description of constraint handler
sepapriority	priority of the constraint handler for separation
enfopriority	priority of the constraint handler for constraint enforcing
checkpriority	priority of the constraint handler for checking feasibility (and propagation)
sepafreq	frequency for separating cuts; zero means to separate only in the root node
propfreq	frequency for propagating domains; zero means only preprocessing propagation
eagerfreq	frequency for using all instead of only the useful constraints in separation, propagation and enforcement, -1 for no eager evaluations, 0 for first only
maxprerounds	maximal number of presolving rounds the constraint handler participates in (-1: no limit)
delaysepa	should separation method be delayed, if other separators found cuts?
delayprop	should propagation method be delayed, if other propagators found reductions?
delaypresol	should presolving method be delayed, if other presolvers found reductions?
needscons	should the constraint handler be skipped, if no constraints are available?
timingmask	positions in the node solving loop where propagation method of constraint handlers should be executed
conshdlrdata	constraint handler data

creates and captures a constraint, and inserts it into the conss array of its constraint handler

Warning: If a constraint is marked to be checked for feasibility but not to be enforced, a LP or pseudo solution may be declared feasible even if it violates this particular constraint. This constellation should only be used, if no LP or pseudo solution can violate the constraint – e.g. if a local constraint is redundant due to the variable's local bounds.

Parameters

cons	pointer to constraint
blkmem	block memory
set	global SCIP settings
name	name of constraint
conshdlr	constraint handler for this constraint
consdata	data for this specific constraint
initial	should the LP relaxation of constraint be in the initial LP? Usually set to TRUE. Set to FALSE for 'lazy constraints'.
separate	should the constraint be separated during LP processing? Usually set to TRUE.
enforce	should the constraint be enforced during node processing? TRUE for model constraints, FALSE for additional, redundant constraints.
check	should the constraint be checked for feasibility? TRUE for model constraints, FALSE for additional, redundant constraints.
propagate	should the constraint be propagated during node processing? Usually set to TRUE.
local	is constraint only valid locally? Usually set to FALSE. Has to be set to TRUE, e.g., for branching constraints.
modifiable	is constraint modifiable (subject to column generation)? Usually set to FALSE. In column generation applications, set to TRUE if pricing adds coefficients to this constraint.
dynamic	is constraint subject to aging? Usually set to FALSE. Set to TRUE for own cuts which are separated as constraints.
removable	should the relaxation be removed from the LP due to aging or cleanup? Usually set to FALSE. Set to TRUE for 'lazy constraints' and 'user cuts'.
stickingatnode	should the constraint always be kept at the node where it was added, even if it may be moved to a more global node? Usually set to FALSE. Set to TRUE to for constraints that represent node data.
original	is constraint belonging to the original problem?
deleteconsdata	has the constraint data to be deleted if constraint is freed?
