+Typical values for the attractor weights are phi1=phi2=2.05.

+The topology defines the communication structure of the swarm. In linear topology, each particle has contact
+to n others in two directions, so there is a linear overlay structure. The grid topology connects a particle
+in 4 directions, while the star variant is completely connected. The random variant just connects each
+particle to k others by random and anew in every generation cycle.
