implements IloMPModeler

IloCplex is the class used to create and solve LP (linear program), QP (program with quadratic terms in the objective function), QCP (quadratically constrained program), and MIP (mixed integer program) Mathematical Programming models. This class implements the IloMPModeler modeling interface and its base interfaces. See the ILOG CPLEX User's Manual for more information about modeling.

Models to be solved by IloCplex should be built using the IloMPModeler (and base interface) methods to construct objects from the following list:

• variables: objects of type IloNumVar and its extensions IloIntVar, IloBoolVar, and IloSemiContVar
• range constraints: objects of type IloRange with (piecewise) linear or quadratic expressions
• other relational constraints: objects of type IloConstraint of the form expr1 relation expr2, where both expressions are linear or quadratic and may optionally contain piecewise linear terms.
• LP matrices: objects of type IloLPMatrix
• a linear, piecewise linear, or quadratic objective: an object of type IloObjective with a (piecewise) linear and/or quadratic expressions
• variable type conversions: objects of type IloConversion
• special ordered sets: objects of type IloSOS1 or IloSOS2

IloCplex stores such models internally in the standard math programming matrix representation:

     Minimize (or Maximize)   c'x + x'Qx
     subject to               L <= Ax <= U
                      a_i'x + x'Q_i x <= r_i, for i = 1, ..., q
                              l <=  x <= u.
  

Thus A is the matrix of linear constraint coefficients, and L and U are the vectors of lower and upper bounds on the vector of variables, x. The Q matrix must be positive semi-definite (or negative semi-definite in the maximization case) and represents the quadratic terms of the objective function. The matrices Q_i must be positive semi-definite and represent the quadratic terms of the i-th quadratic constraint, and the a_i are vectors containing the correponding linear terms. For more about the Q_i, see the chapter about QCP in the ILOG CPLEX User's Manual.

If the model contains integer, Boolean, or semi-continuous variables, or if the model has special ordered sets (SOSs), the model is referred to as a mixed integer program (MIP). You can query whether the active model is a MIP with the method IloCplex.isMIP.

A model with quadratic terms in the objective is referred to as a mixed integer quadratic program (MIQP) if it is also a MIP, and a quadratic program (QP) otherwise. You can query whether the active model has a quadratic objective by calling method IloCplex.isQO.

A model with quadratic constraints is referred to as a quadratically constrained program (MIQCP) if it is also a MIP, and as QCP otherwise. You can query whether the active model is quadratically constrained by calling the method IloCplex.isQC. A QCP may or may not have a quadratic objective; that is, a given problem may be both QP and QCP. Likewise, a MIQCP may or may not have a quadratic objective; that is, a given problem may be both MIQP and MIQCP.

If there are no quadratic terms in the objective, no integer constraints, and the problem is not quadratically constrained, it is called a linear program (LP).

If there are no quadratic terms in the objective, and the problem is not quadratically constrained, but there are integer variables, it is called a mixed integer linear program (MILP).

Special ordered sets (SOS) fall outside the conventional representation in terms of A and Q matrices and are stored separately.

Information related to the matrix representation of the model can be queried through these methods:

• IloCplex.getNcols for querying the number of columns of A,
• IloCplex.getNrows for querying the number of rows of A; that is, the number of linear constraints,
• IloCplex.getNQCs for querying the number of quadratic constraints,
• IloCplex.getNNZs for querying the number of nonzero elements in A, and
• IloCplex.getNSOSs for querying the number of SOSs.

Additional information about the active model can be obtained through iterators defined on the different types of modeling objects.

IloCplex effectively treats all models as MIQCP models. That is, it allows the most general case, although the solution algorithms make efficient use of special cases, such as the absence of quadratic terms in the formulation.

The method IloCplex.solve is used to solve the active model. It begins by solving the root relaxation of the MIQCP model, where all integrality constraints and SOSs are ignored. If the model has no integrality constraints or SOSs, then the optimization is complete once the root relaxation is solved. Otherwise, IloCplex uses a branch and cut procedure to reintroduce the integrality constraints and SOS constraints. See the ILOG CPLEX User's Manual for more information about branch and cut.

Most users can simply call solve to solve their models. However, several parameters are available for users who require more control. Perhaps the most important one is IloCplex.IntParam.RootAlg, which determines the algorithm used to solve the root relaxation. Possible settings, as defined in IloCplex.Algorithm, are:

• IloCplex.Algorithm.Auto
IloCplex automatically selects an algorithm. This is the default setting.
• IloCplex.Algorithm.Primal
  Use the primal simplex algorithm.
• IloCplex.Algorithm.Dual
  Use the dual simplex algorithm.
• IloCplex.Algorithm.Network
  Use network simplex on the embedded network part of the model, followed by dual simplex on the entire model.
• IloCplex.Algorithm.Barrier
  Use the barrier algorithm.
• IloCplex.Algorithm.Sifting
  Use the sifting algorithm. This option is not available for quadratic problems. If selected nonetheless, IloCplex defaults to the IloCplex.Algorithm.Auto setting.
• IloCplex.Algorithm.Concurrent
  Use several algorithms concurrently. This option is not available for quadratic problems. If selected nonetheless, IloCplex defaults to the IloCplex.Algorithm.Auto setting.

Numerous other parameters allow you to control algorithmic aspects of the optimizer. See IloCplex.IntParam, IloCplex.DoubleParam, and IloCplex.StringParam for further information. Parameters are set with the method setParam.

Even higher levels of control can be achieved through the use of goals (see IloCplex.Goal) or callbacks (see IloCplex.Callback and its extensions).

The solve method returns a Boolean value indicating whether (true) or not (false) a solution (not necessarily the optimal one) has been found. Further information about the solution can be queried with the method getStatus. The return code of type IloCplex.Status indicates whether the solution is feasible, bounded, or optimal, or if the model has been proven to be infeasible or unbounded. See IloCplex.Status for more information.

The method IloCplex.getCplexStatus provides more detailed information about the status of the optimizer after IloCplex.solve returns. For example, it can provide information about why the optimizer terminated prematurely (time limit, iteration limit, etc.). The methods IloCplex.isPrimalFeasible and IloCplex.isDualFeasible can be used to determine whether a primal or dual feasible solution has been found and can be queried.

The most important solution information computed by IloCplex are usually the solution vector and the objective function value. These can be queried with the methods IloCplex.getValue and IloCplex.getObjValue, respectively. Most optimizers also compute additional solution information. (for example, dual values, reduced costs, simplex bases, etc.) This additional information can also be queried through various methods of IloCplex. If you attempt to retrive solution information that is not available from a particular optimizer, IloCplex will throw an exception.

If you are solving an LP and a basis is available, the solution can be further analyzed by performing sensitivity analysis. This information tells you how sensitive the solution is with respect to changes in variable bounds, constraint bounds, or objective coefficients. The information is computed and accessed with the methods IloCplex.getBoundSA, IloCplex.getRangeSA, IloCplex.getRHSSA, and IloCplex.getObjSA.

An important consideration when you access solution information is the numeric quality of the solution. Since IloCplex performs arithmetic operations using finite precision, solutions are always subject to numeric errors. For most problems, numeric errors are well within reasonable tolerances. However, for numerically difficult models, you are advised to verify the quality of the solution using the method IloCplex.getQuality, which offers a variety of quality measures.

addUserCut

                                      throws IloException

This is an advanced method.

Important:

Advanced methods typically demand a profound understanding of the algorithms used by ILOG CPLEX. Thus they incur a higher risk of incorrect behavior in your application, behavior that can be difficult to debug. Therefore, ILOG encourages you to consider carefully whether you can accomplish the same task by means of other methods instead.

This method adds cut as a user cut to the invoking IloCplex object. Unlike regular constraints that are added to the model, user cuts are by default left out of the optimization until they are violated. It is only after a node solution violates a user cut that the cut is added to the relaxation and will be used from then on. Unlike lazy constraints, user cuts must not reduce the feasible region of the problem; they can only strengthen the relaxation; otherwise, incorrect solutions can result.

When columns are deleted from the active model, all user cuts are deleted as well and need to be added again if they should be considered. Use clearUserCuts to remove all user cuts from the invoking IloCplex object.

Parameters:

cut - The user cut to be added. The cut must be linear.

Returns:

The added user cut.

This method adds cut as a lazy constraint to the invoking IloCplex object. The constraint cut is copied into the lazy constraint pool; the cut itself is not part of the pool, so changes to cut after it has been copied into the lazy constraint pool will not affect the lazy constraint pool.

Lazy constraints added with addLazyConstraint are typically constraints of the model that are not expected to be violated when left out. The idea behind this is that the LPs that are solved when the MIP is being solved can be kept smaller when these constraints are not included. IloCplex will, however, include a lazy constraint in the LP as soon as the constraint is violated. In other words, the solution computed by IloCplex makes sure that all the lazy constraints that have been added are satisfied.

By contrast, if the constraint does not change the feasible region of the active model but only strengthens the formulation, it is referred to as a user cut. User cuts can be added to IloCplex by addLazyConstraint, but it is generally preferable to do so with addUserCuts. It is an error, however, to add lazy constraints by means of addUserCuts.

When columns are deleted from the active model, all lazy constraints are deleted as well and need to be recopied into the lazy constraint pool. Otherwise, use clearLazyConstraints to clear the list of lazy constraints.

Parameters:

cut - The constraint to be added as a lazy constraint. The constraint must be linear.

Returns:

The constraint added as a lazy constraint.

Adds the constraint cut as a cut to the invoking IloCplex object. The cut does not become part of the model; it is only copied when the method addCut is invoked. Thus, cut may be deleted or modified after addCut has been called, and the change will not affect the invoking IloCplex object.

Cuts are not part of the root problem; they are considered on an as-needed basis. A solution computed by IloCplex is guaranteed to satisfy all cuts.

When columns are deleted from the active model, all cuts are deleted as well and need to be added again if they should be considered. Otherwise, use clearCuts to clear all cuts that have been added.

Parameters:

exportModel

public void exportModel(java.lang.String name)
                 throws IloException

Writes the active model to a file. The file format is determined by the extension of the filename. The following extensions are recognized:

• .sav
• .mps
• .lp
• .sav.gz (if gzip is properly installed)
• .mps.gz (if gzip is properly installed)
• .lp.gz (if gzip is properly installed)

If no name has been assigned to a variable or range (that is, getName returns null for that variable or range), IloCplex uses a default name when writing the model (or in the optimization log). Default names are of the form IloXj for variables and IloCi, where i and j are internal indices of IloCplex.

Parameters:

name - The name of the file to which the model is written. The extension of the filename determines the format in which to write the model file.

IloException

importModel

public void importModel(java.lang.String name)
                 throws IloException

Reads a model into the active model. The format of the file is determined by the extension of the filename. The following extensions are recognized:

• .sav
• .mps
• .lp
• .sav.gz (if gzip is properly installed)
• .mps.gz (if gzip is properly installed)
• .lp.gz (if gzip is properly installed)

When reading a file, the existing active model is first cleaned out and then new modeling objects, as required by the input file, are added to it. In particular, one IloObjective object and one IloLPMatrix object are always added to the active model. The IloLPMatrix object will contain all the constraints of the imported model. IloSOS1 and IloSOS2 objects are added as needed.

Parameters:

name - The name of the file from which the model is read. The extension of the filename determines the format in which to read the model file.

Specifies a starting point for the next invocation of method solve.

Starting point information is exploited at the next call of method solve. In particular, if the active model is an LP or QP, and parameter IloCplex.IntParam.RootAlg is IloCplex.Algorithm.Primal or IloCplex.Algorithm.Dual, the starting point information provided with this method is used to construct a starting basis for the Simplex method.

If the active model is a MIP, only primal starting point values for the variables are used. A value must be specified for every variables of type IloNumVarType.Int or IloNumVarType.Boolean. If the provided values are compatible with an integer feasible solution, that solution becomes the incumbent for the next search; otherwise the starting information is ignored. Parameter IloCplex.BooleanParam.MIPStart must be turned on (set to true) for the starting point information to be used when solving a MIP.

The starting point information is provided in the parameters of this method. null can be passed for any of the parameters. However, if x or dj are not null, var must not be null. Similarly, if slack or pi are not null, rng must not be null.

For all variables given in var, x[j] specifies the starting primal value for variable var[j]. Similarly, dj[j] specifies the starting reduced cost for variable var[j]. For all ranges specified in rng, slack[i] specifies the starting slack value for rng[i]. Similarly, pi[i] specifies the starting dual value for rng[i].

Parameters:

x - The array of starting primal values for var.

dj - The array of starting reduced costs for var.

var - The array of variables for which to set starting point information.

slack - The array of starting slack values for rng.

pi - The array of starting dual values for rng.

This function computes a minimal relaxation of variable and/or constraint bounds that make the active model feasible.

For each bound, the user may specify a preference value indicating how much a relaxation of that bound is acceptable. A negative or zero (0) value indicates that the corresponding bound must not be relaxed. Typically, values ≥ 1 should be used.

If enough bounds were allowed to be relaxed, the method returns with suggested relaxed bounds that would make the active model feasible. These bounds are chosen in such a way that the relaxation is minimal in the sense that the sum of relaxation/preference over all variables and constraints is minimized. A solution vector for the model relaxed in this way will be available.

When the optimize parameter is set to true, this method also tries finds the optimal solution of the minimally relaxed model.

use

public void use(IloCplex.Callback cb)
         throws IloException

Installs a user-written callback.

Callbacks are objects with a user-written method main that are called regularly during the optimization of the active model. This object must be implemented as a class derived from a subclass of IloCplex.Callback class, and the abstract method main must be implemented for this class.

There are several places where the IloCplex algorithms call a callback. IloCplex provides several different types of callbacks, and each is implemented as a specific subclass of IloCplex.Callback.

IloCplex can use only one callback of a given type at a time. Thus, when calling method use several times with callbacks of the same type, only the callback passed at the last call of method use will be executed during the optimization. However, callbacks of different types can be used simultaneously.

Parameters:

cb - The callback to be used from now on. The type of the callback object being passed determines which callback is being installed. If a callback of the same type has previously been installed, the new callback will replace the old one.

IloException

clearCallbacks

public void clearCallbacks()
                    throws IloException

Removes all callbacks from the invoking IloCplex object.

getRay

public ilog.concert.IloLinearNumExpr getRay()
                                     throws IloException

This is an advanced method.

Important:

Advanced methods typically demand a profound understanding of the algorithms used by ILOG CPLEX. Thus they incur a higher risk of incorrect behavior in your application, behavior that can be difficult to debug. Therefore, ILOG encourages you to consider carefully whether you can accomplish the same task by means of other methods instead.

This method returns a linear expression representing an unbounded direction for the active model if it has been proven unbounded by one of the simplex methods. If a*x + b*y is the returned by this method, it represents an unbounded direction vector with an x coordinate of a and y coordinate of b.

Returns:

A linear expression describing unbounded direction for the unbounded active model

IloException

dualFarkas

public double dualFarkas(ilog.concert.IloConstraint[] rng,
                         double[] y)
                  throws IloException

This is an advanced method.

Important:

Advanced methods typically demand a profound understanding of the algorithms used by ILOG CPLEX. Thus they incur a higher risk of incorrect behavior in your application, behavior that can be difficult to debug. Therefore, ILOG encourages you to consider carefully whether you can accomplish the same task by means of other methods instead.

This method returns a Farkas proof of infeasibility for the active LP model after it has been proven to be infeasible by one of the simplex optimizers. For every constraint i of the active LP this method computes a value y[i] such that y'A >= y'b, where A denotes the constraint matrix. For more detailed information about the Farkas proof of infeasibility, see the C function CPXdualfarkas, documented in the reference manual of the Callable Library.

Parameters:

rng - Array of length getNrows where constraints corresponding to the values in y are returned.

y - array of length getNrows.

Returns:

The value of y'b - y'A z for vector z defined such that z[j] = ub[j] if y'A[j] > 0 and z[j] = lb[j] if y'A[j] < 0 for all variables j.

                               double[] x)
                        throws IloException

Returns a vector proving that the Q matrix of QP is not positive semi-definite. When solving QPs, the quadratic terms of the objective function must form a positive semi-definite Q matrix (for a minimization problem, or negative semi-definite otherwise). If IloCplex finds this not be true, it will discontinue the optimization. In such cases, this method can be used to compute assignments to all variables such that the quadratic term of the objective function evaluates to a negative value (x'Q x < 0 in matrix terms) to prove the indefiniteness.

Parameters:

var - An array of length getNcols where the variables of the active model are returned.

x - An array of length getNcols. By setting var[j] to x[j] for all variables, the quadratic term of the objective function evaluates to a negative value.

IloException

end

public void end()

Releases the IloCplex license held by the invoking object, and all the memory allocated by it. When you no longer use an IloCplex object and any Concert model created with it, you should call the method end to release the license. After a call of the method end, the invoking IloCplex object and all objects that have been created with it (such as variables and constraints) may no longer be used. Attempting to use them subsequently will cause the exception IloCplex.CplexEndedException to be thrown.

Parameters:

cut - The constraints to added to the current subtree.

Returns:

A constraint goal for adding the constraints in cut.

globalCutGoal

public final IloCplex.Goal globalCutGoal(ilog.concert.IloConstraint cut)
                                  throws IloException

Creates and returns a global cut goal for the constraint cut. When this goal is executed, the constraint will be added to the active model as a global cut. This constraint will be respected at every node explored from that point on, not just those in the current subtree.

Parameters:

cut - The constraint to added as a global cut.

Returns:

A global cut goal for adding the constraint cut as a global cut.

globalCutGoal

public final IloCplex.Goal globalCutGoal(ilog.concert.IloConstraint[] cut)
                                  throws IloException

Creates and returns a global cut goal for the constraints specified in array cut. When this goal is executed, the constraints will be added to the active model as global cuts. These constraints will be respected at every node explored from that point on, not just those in the current subtree.

Parameters:

cut - The constraints to added as global cuts.

Returns:

A global cut goal for adding the constraints cut as global cuts.

solutionGoal

public final IloCplex.Goal solutionGoal(ilog.concert.IloNumVar[] vars,
                                        double[] vals)
                                 throws IloException

Creates and returns a solution goal.

When the solution goal is executed, it attempts to inject the solution specified by setting the variables listed in vars to the corresponding values listed in val as a new incumbent.

IloCplex will not blindly accept such a solution. Instead, it will make sure that this solution is compatible with both the model and the goals. When checking feasibility with goals, it will check feasibility with both goals that have already been executed and goals that are still on the goal stack. Thus, in particular, IloCplex will reject any solution that is not compatible with the branching that has been done so far. It then continues by checking compatibility with the goals still remaining on the goal stack, including those that may get created by them. Only if the proposed solution remains feasible and has a better objective value than the current incumbent will it be used to replace the current incumbent.

Parameters:

vars - An array of variables for which solution values are specified.

vals - The array of solution values for the variables in vars. Value vals[j] is the proposed solution value for variable vars[j].

Returns:

The goal that injects the solution.
