Smart Agents Donít Need Kin - Evolving Specialisation and Cooperation

In a previous paper (Hales 2002) we presented simulation results that demonstrated
the evolution of “tag based” groups composed of cooperative (in-group altruistic)
individual agents performing specialised functions. We hypothesised that a key to
the efficiency of the specialisation process was the “searching strategy” employed
by agents to locate other members of their group with the required skills for given
task contexts. Specifically, we hypothesised that “smart” searching strategies would
improve efficiency over the “dumb” strategies implemented so far. In this paper we
test this hypothesis. Even when the costs for smart searching are much higher, very
substantial increases in donation between non-kin are produced.
