PERPETUAL EMERGENCE. “Substantial effort in the genetic programming community is dedicated to exploring avenues for designing solutions to hard problems. In an ideal situation the solution would adapt to unseen new problems in a satisfactory manner. In our view, this can be achieved to a great extent if mechanisms for allowing perpetual emergence and autonomous response to emerging properties, not requiring external intervention, are put in place.”
