public class LSModel
extends java.lang.Object
```
Mathematical optimization model. A model is composed of expressions (some of which are decisions), organized as a tree. Then, some expressions of the model can be constrained or optimized. Once your optimization model is created and closed, the solver can be launched to resolve it. Note that you cannot modify a model which has been closed: you must reopen it (with open()) or instantiate another LocalSolver environment to optimize another model.

  - createIntExternalFunction
```
public LSExpression createIntExternalFunction(LSIntExternalFunction func)
```
    Creates an integer external function. The argument must implement LSIntExternalFunction. When the external function is called, the argument values will be made accessible to your function through the LSExternalArgumentValues.
    
    Once you have instantiated it, you have to use call(LSExpression... operands) to call it in your model.
    
    Note 1: Most of the time your external function will be called when the solver is in state LSState.Running. Do not attempt to call any method of the solver (to retrieve statistics, values of LSExpressions or whatever) in that state or an exception will be thrown. The only accessible function is LocalSolver.stop().
    
    Note 2: Your functions must be thread-safe. According to the "nbThreads" parameter, LocalSolver can be multi-threaded. In that case, your external functions must be thread safe. If you cannot guarantee the thread-safety of your code, we strongly recommend you to limit the search of LocalSolver to one thread with LSParam.setNbThreads(int).
    
    Note 3: You can provide additional data for your function (such as lower and upper bounds) with the help of the LSExternalContext associated with your function (see LSExpression.getExternalContext().
    
    Parameters:
    
    func - External function to call.
    
    Returns:
    
    The expression associated with the function.

```
public LSExpression createDoubleExternalFunction(LSDoubleExternalFunction func)
```
    Creates a double external function. The argument must implement LSDoubleExternalFunction. When the external function is called, the argument values will be made accessible to your function through the LSExternalArgumentValues.
    
    Once you have instantiated it, you have to use call(LSExpression... operands) to call it in your model.

    Once you have instantiated it, you have to use call(LSExpression... operands) to call it in your model.
    
    Note: You can provide additional data and parameters for your function (such as the maximum number of evaluations) with the help of the LSExternalContext associated with your function (see LSExpression.getExternalContext()).
    
    Parameters:
    
    func - External function to call.

```
public LSExpression createDoubleArrayExternalFunction(LSDoubleArrayExternalFunction func)
```
    Creates a double array external function. The argument must implement LSDoubleArrayExternalFunction. When the external function is called, the argument values will be made accessible to your function through the LSExternalArgumentValues.
    
    Once you have instantiated it, you have to use call(LSExpression... operands) to call it in your model.
    
    Note: You can provide additional data and parameters for your function (such as the maximum number of evaluations) with the help of the LSExternalContext associated with your function (see LSExpression.getExternalContext()).
    
    Parameters:
    
    func - External function to call.
    
    Returns:
    
    The expression associated with the function.

  - createLambdaFunction
```
public LSExpression createLambdaFunction(LSLambdaFunction0 functor)
```
    Creates a lambda function without arguments. A lambda function is a particular expression composed of two parts:
    
    The arguments of the function (which are also LSExpressions of type LSOperator.Argument.
    
    The body of the function. The body is an LSExpression that will be used to evaluate the result of the function. The body can be any LSExpression composed of any operands and operators supported by LocalSolver. Thus, the body expression can use the arguments of the function but can also capture and refer to expressions declared outside of the function.
    
    The function you provide will not be used directly during the solving process, but will be evaluated once by the API. At the end of the evaluation of your function, the returned LSExpression will be used as the body of the LocalSolver function.
    Parameters:
    
    functor - A function (LSLambdaFunction0) that returns an LSExpression that will be used as the body of the new LocalSolver function you want to create.
    
    Returns:
    
    Expression of type LSOperator.LambdaFunction.

public void removeObjective(int objectiveIndex)
```
    Removes the objective at the given position in the list of objectives. Note that the objectives created after the removed one have their index decreased by 1. Phases are not modified when an objective is removed. It is the user's responsibility to change the objective index of each phase to keep it coherent (with LSPhase.setOptimizedObjective(int)), or to disable it (with LSPhase.setEnabled(boolean)). Only allowed in state LSState.Modeling.
    
    Parameters:
    
    objectiveIndex - position of the objective to remove.
    
    Since:

    Returns:
    
    Objective direction.
  - getNbOperands
```
public int getNbOperands()
```
    Gets the number of operands in the model. This corresponds to the number of operands for all expressions declared in the model. It is an analog of the number of non zeros in matrix model encountered in mathematical programming: it gives an hint about the size and the density of your model.
    
    Returns:
    
    Number of operands.
  - close
```
public void close()
```
    Closes the model. Only allowed in state LSState.Modeling. When this method is called, the solver is placed in state LSState.Stopped. Once the model is closed, no expressions, constraints or objectives can be added or removed unless the model is reopened. The model must be closed before starting its resolution.
  - open
```
public void open()
```
    Reopens the model. Only allowed in state LSState.Stopped. When this method is called, the solver is placed in state LSState.Modeling. In this state, the model can be modified: it is possible to add new expressions, constraints or objectives, modify expression operands, and remove existing constraints and objectives. However, existing expressions cannot be deleted. Note that the solution will be reset when the model is closed again.
  - isClosed
```
public boolean isClosed()
```
    Returns true if the model is closed, false otherwise.
    
    Returns:
    
    True if the model is closed.
