- Method Detail
  - getOptimizable
```
public Optimizable getOptimizable()
```
    Specified by:
    
    getOptimizable in interface Optimizer
  - isConverged
```
public boolean isConverged()
```
    Specified by:
    
    isConverged in interface Optimizer
  - setLineOptimizer
```
public void setLineOptimizer(LineOptimizer.ByGradient lineOpt)
```
    Sets the LineOptimizer.ByGradient to use in L-BFGS optimization.
    
    Parameters:
    
    lineOpt - line optimizer for L-BFGS
  - setTolerance
```
public void setTolerance(double newtol)
```
  - setEvaluator
```
public void setEvaluator(OptimizerEvaluator.ByGradient eval)
```
  - getIteration
```
public int getIteration()
```
  - optimize
```
public boolean optimize()
```
    Specified by:
    
    optimize in interface Optimizer
  - optimize
```
public boolean optimize(int numIterations)
```
    Specified by:
    
    optimize in interface Optimizer
  - reset
```
public void reset()
```
    Resets the previous gradients and values that are used to approximate the Hessian. NOTE - If the Optimizable object is modified externally, this method should be called to avoid IllegalStateExceptions.
