C# Class SwarmOps.Optimizers.PSO

Particle Swarm Optimization (PSO) originally due to Eberhart et al. (1, 2). This is a 'plain vanilla' variant which can have its parameters tuned (or meta-optimized) to work well on a range of optimization problems. Generally, however, the DE optimizer has been found to work better.
