C# Класс SwarmOps.Optimizers.DE

Differential Evolution (DE) optimizer originally due to Storner and Price (1). This simple and efficient variant is based on the The Joker variant by Pedersen et al. (2). It has been found to be very versatile and works well on a wide range of optimization problems, but may require tuning (or meta-optimization) of its parameters.
