org.apache.commons.math3.exception.MathIllegalStateException
This class implements the simplex concept. It is intended to be used in conjunction with {@link SimplexOptimizer}.
The initial configuration of the simplex is set by the constructors {@link #AbstractSimplex(double[])} or {@link #AbstractSimplex(double[][])}. The other {@link #AbstractSimplex(int) constructor} will set all stepsto 1, thus building a default configuration from a unit hypercube.
Users must call the {@link #build(double[]) build} method in orderto create the data structure that will be acted on by the other methods of this class. @see SimplexOptimizer @since 3.0
