@Deprecated public abstract class AbstractSimplex extends Object implements OptimizationData
SimplexOptimizer.
 AbstractSimplex(double[]) or AbstractSimplex(double[][]).
 The other constructor will set all steps
 to 1, thus building a default configuration from a unit hypercube.
 build method in order
 to create the data structure that will be acted on by the other methods of
 this class.SimplexOptimizer| Modifier | Constructor and Description | 
|---|---|
| protected  | AbstractSimplex(double[] steps)Deprecated.  The start configuration for simplex is built from a box parallel to
 the canonical axes of the space. | 
| protected  | AbstractSimplex(double[][] referenceSimplex)Deprecated.  The real initial simplex will be set up by moving the reference
 simplex such that its first point is located at the start point of the
 optimization. | 
| protected  | AbstractSimplex(int n)Deprecated.  Build a unit hypercube simplex. | 
| protected  | AbstractSimplex(int n,
               double sideLength)Deprecated.  Build a hypercube simplex with the given side length. |
