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, and, where deemed helpful, some promising paths to its solution are indicated

Machine Learning for Fluid Mechanics
The field of fluid mechanics is rapidly advancing, driven by unprecedented
volumes of data from field measurements, experiments and large-scale
simulations at multiple spatiotemporal scales. Machine learning offers a wealth
of techniques to extract information from data that could be translated into
knowledge about the underlying fluid mechanics. Moreover, machine learning
algorithms can augment domain knowledge and automate tasks related to flow
control and optimization. This article presents an overview of past history,
current developments, and emerging opportunities of machine learning for fluid
mechanics. It outlines fundamental machine learning methodologies and discusses
their uses for understanding, modeling, optimizing, and controlling fluid
flows. The strengths and limitations of these methods are addressed from the
perspective of scientific inquiry that considers data as an inherent part of
modeling, experimentation, and simulation. Machine learning provides a powerful
information processing framework that can enrich, and possibly even transform,
current lines of fluid mechanics research and industrial applications.Comment: To appear in the Annual Reviews of Fluid Mechanics, 202
The Past, Present, and Future of Artificial Life
For millennia people have wondered what makes the living different from the non-living. Beginning in the mid-1980s, artificial life has studied living systems using a synthetic approach: build life in order to understand it better, be it by means of software, hardware, or wetware. This review provides a summary of the advances that led to the development of artificial life, its current research topics, and open problems and opportunities. We classify artificial life research into fourteen themes: origins of life, autonomy, self-organization, adaptation (including evolution, development, and learning), ecology, artificial societies, behavior, computational biology, artificial chemistries, information, living technology, art, and philosophy. Being interdisciplinary, artificial life seems to be losing its boundaries and merging with other fields
Modelling Early Transitions Toward Autonomous Protocells
This thesis broadly concerns the origins of life problem, pursuing a joint
approach that combines general philosophical/conceptual reflection on the
problem along with more detailed and formal scientific modelling work oriented
in the conceptual perspective developed. The central subject matter addressed
is the emergence and maintenance of compartmentalised chemistries as precursors
of more complex systems with a proper cellular organization. Whereas an
evolutionary conception of life dominates prebiotic chemistry research and
overflows into the protocells field, this thesis defends that the 'autonomous
systems perspective' of living phenomena is a suitable - arguably the most
suitable - conceptual framework to serve as a backdrop for protocell research.
The autonomy approach allows a careful and thorough reformulation of the
origins of cellular life problem as the problem of how integrated autopoietic
chemical organisation, present in all full-fledged cells, originated and
developed from more simple far-from-equilibrium chemical aggregate systems.Comment: 205 Pages, 27 Figures, PhD Thesis Defended Feb 201
