Open Problems in Artificial Life
This article lists fourteen open problems in artificial life, each of which is a grand challenge requiring a major advance on a fundamental issue for its solution. Each problem is briefly explained,
Food-web formation with recursive evolutionary branching.
Open-Ended Evolution: Perspectives from the OEE Workshop in York
We describe the content and outcomes of the First Workshop on Open-Ended Evolution: Recent Progress and Future Milestones (OEE1), held during the ECAL 2015 conference at the University of York, UK,
Once More Unto the Breach: Co-evolving a robot and its simulator
This paper presents a new co-evolutionary approach, which is called the estimation-exploration algorithm, that automatically adapts the robot simulator using behavior of the target robot, and adaptation of the robot using the robot Simulator.
Adaptability and Diversity in Simulated Turn-taking Behavior
It is claimed that there is a complementary relationship between robustness and adaptability and by investigating the recoupling of agents from different GA generations, the emergence of a new turn-taking behavior is reported.
Homeostasis and Rein Control: From Daisyworld to Active Perception
A new and much simplified version of the Daisyworld model is presented, demonstrating that the combination of any ‘Hat function’ with any feedback, positive or negative, can lead to homeostasis through ‘Rein Control’.
Making a Robot Dance to Music Using Chaotic Itinerancy in a Network of FitzHugh-Nagumo Neurons
We propose a technique to make a robot execute free and solitary dance movements on music, in a manner which simulates the dynamic alternations between synchronisation and autonomy typically observed
Artificial Chemistry: Computational Studies on the Emergence of Self-Reproducing Units
It is demonstrated that proto-cell structures that maintain and reproduce themselves autonomously emerge from a non-organized initial configuration, and it is suggested that a metabolic system that produces membranes can be selected in the chemical evolution of a pre-cellular stage.
Motility at the Origin of Life: Its Characterization and a Model
It is suggested that processes on intermediate time scales could have already been operative in prebiotic systems and may have facilitated and constrained changes occurring in the faster- and slower-paced time scales of chemical self-individuation and evolution by natural selection, respectively.
