The Cost of Communication: Environmental Pressure and Survivability in mEDEA

Steyven, Andreas; Hart, Emma; Paechter, Ben

Abstract

We augment the mEDEA algorithm to explicitly account for
the costs of communication between robots. Experimental
results show that adding a costs for communication exerts
environmental pressure to implicitly select for genomes that
maintain high energy levels. We compare our two methods
which vary broadcasting based on the individuals fitness to
vanilla mEDEA bundled with an explicit selection method
under these new conditions and find that biasing broadcast-
ing has a negative effect on survivability.
