C# Класс SwarmOps.Optimizers.JDE

Differential Evolution (DE) optimizer originally due to Storner and Price (1). jDE variant due to Brest et al. (2). This variant claims to be 'self-adaptive' in that it claims to eliminate the need to choose two parameters of the original DE, but in reality it introduces an additional 6 parameters, so the jDE variant now has 9 parameters instead of just 3 of the original DE.
