IloCplex::HeuristicCallbackI
protected IloAlgorithm::Status getStatus()
This method returns the status of the solution found by the instance of IloCplex at the
current node during the last call to solve (which may have been called directly in the
callback or by IloCplex when processing the node).
The enumeration IloAlgorithm::Status lists the possible status values.
protected IloBool isDualFeasible()
This method returns IloTrue if the solution provided by the last solve call is dual
feasible. Note that an IloFalse return value does not necessarily mean that the
solution is not dual feasible. It simply means that the relevant algorithm was not able to
conclude it was dual feasible when it terminated.
protected IloBool isPrimalFeasible()
This method returns IloTrue if the solution provided by the last solve call is primal
feasible. Note that an IloFalse return value does not necessarily mean that the
solution is not primal feasible. It simply means that the relevant algorithm was not able
to conclude it was primal feasible when it terminated.
protected void setBounds(const IloIntVarArray var,
const IloNumArray lb,
const IloNumArray ub)
For each variable in the array var, this method sets its upper bound to the
corresponding value in the array ub and its lower bound to the corresponding value in
the array lb. Setting bounds has no effect beyond the scope of the current invocation of
the callback.
protected void setBounds(const IloNumVarArray var,
const IloNumArray lb,
const IloNumArray ub)
For each variable in the array var, this method sets its upper bound to the
corresponding value in the array ub and its lower bound to the corresponding value in
the array lb. Setting bounds has no effect beyond the scope of the current invocation of
the callback.
protected void setBounds(const IloIntVar var,
IloNum lb,
IloNum ub)
This method sets the lower bound to lb and the upper bound to ub for the variable var
at the current node. Setting bounds has no effect beyond the scope of the current
invocation of the callback.
protected void setBounds(const IloNumVar var,
IloNum lb,
IloNum ub)
