weight

interval<double> ultra::parameters::de_parameters::weight {0.5, 1.0}

Weighting factor range (aka differential factor range).

It has been found recently that selecting the weight from the interval [0.5, 1.0] randomly for each generation or for each difference vector, a technique called dither, improves convergence behaviour significantly, especially for noisy objective functions.
