Detailed Description

Random predictor computation class

This class computes the predictor direction where the solution component is filled with random values and the parameter component equal to 1. Each componenet of the solution vector of the predictor is given by where is a random value between -1 and 1, is the corresponding component of the solution vector, and is a parameter.

The parameters used by this class supplied in the constructor or reset method are:

• "Epsilon" - as defined above (Default 1.0e-3)
