This constant refers to using the Polak-Riviere algorithm (i.e. {@link MultiDimensional#derivPolakRiviere}) which is then used in conjunction with the Simulated Annealing approach in order to find the global extremum of a multi-dimensional optimization problem with a differentiable object function.
