Information exchange in multiple cooperating swarms

This paper investigates the idea of having two cooperating swarms exchanging information in order to solve an optimization problem. The information being exchanged between the two swarms is an important factor that affects the quality of the obtained solution. The information to be shared between the two swarms has to be carefully selected depending on the model being used. This paper compares two types of information to be exchanged, namely the global best and the best particle. It is shown that exchanging the best particles leads to better results than only sharing the global best. This paper also addresses the idea of exchanging the best p particles between the two swarms.
