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