ILOG CPLEX C++ API 9.0 Reference Manual

IloCplex::GoalI
This method returns the value of the variable var in the solution of the current node
relaxation.
public IloNum getValue(const IloNumVar var)
This method returns the value of the variable var in the solution of the current node
relaxation.
public IloNum getValue(const IloExpr expr)
This method returns the value of the expression expr in the solution of the current node
relaxation.
public void getValues(IloNumArray vals,
const IloIntVarArray vars)
This method puts the current node relaxation solution value of each variable in the array
vars into the corresponding element of the array vals.
public void getValues(IloNumArray vals,
const IloNumVarArray vars)
This method puts the current node relaxation solution value of each variable in the array
vars into the corresponding element of the array vals.
public static IloCplex::Goal GlobalCutGoal(IloConstraintArray con)
This method creates a goal that when executed adds the constraints (provided in the
paramter array con) as global cuts to the model. These global cuts must be valid for the
entire model, not only for the current subtree. In other words, these global cuts will be
respected at every node.
IloCplex takes over memory managment for the cuts passed to the method
GlobalCutGoal. Thus IloCplex will call the method end as soon as it can be
discarded after the goal executes. Calling end yourself or the constraints in the array
con passed to method GlobalCutGoal or the array itself is an error and must be
avoided.
public static IloCplex::Goal GlobalCutGoal(IloConstraint con)
This method creates a goal that when executed adds the constraint con (provided as a
parameter) as global cuts to the model. These global cuts must be valid for the entire
model, not only for the current subtree. In other words, these global cuts will be
respected at every node.
IloCplex takes over memory managment for the cut passed to the method
GlobalCutGoal. Thus IloCplex will call the method end as soon as it can be
discarded after the goal executes. Calling end yourself for the constraint passed to
method GlobalCutGoal is an error and must be avoided.
public IloBool hasIncumbent()
This method returns IloTrue if an integer feasible solution has been found.
