The evolutionary emergence of socially intelligent agents

Channon, A. D., and R. I. Damper. “The evolutionary emergence of socially intelligent agents.” (1998): 41-49.

Evolutionary emergence is the key to generating increasingly socially intelligent
agents. In order to generate agents with novel behaviors beyond our manual design
capability, long-term incremental evolution with continuing emergence within a social
environment is called for. Purely artificial selection models are argued to be
fundamentally inadequate for this calling and a new natural selection system
containing simple virtual agents is presented. Each agent is controlled by a
genetically determined neural network − controllers suited to both incremental
evolution and the goal of intelligent behaviors. Resulting evolutionary emergent
social behaviors are reported alongside their neural correlates. In one example, the
collective behavior of one species clearly provides a selective force which is
overcome by another species, demonstrating the perpetuation of evolutionary
emergence via naturally-arising social coevolution.
