This document is both a synthesis of current notions about complex systems and a practical approach description. A disambiguation is proposed and exposes possible reasons for controversies related to causation and emergence. Theoretical considerations about simulations are presented. A justification is then given for the development of practical tools and techniques for the investigation of complex systems. A methodology for the usage of these tools is finally suggested, illustrated by… 

A New Kind Methodology for Controlling Complex Systems

The paper introduces a formal way to completely describe the formation and dynamics of emergence in complex systems and indicates the Emergence-Oriented Control methodology that contains three kinds of basic control schemes: the direct control, the system re-structuring and the system calibration.

Extending Life Concepts to Complex Systems

Using notions such as 'birth' or 'lifespan' as transversal concepts may be of heuristic value for the generic characterization of complex systems, opening up new lines of research for improving their definition.

Models and people: An alternative view of the emergent properties of computational models

The use of computer models to support individual and shared decision making could potentially have implications far wider than the ones often discussed within the Information and Communication Technologies community in terms of computational power and network communication.

Emergence and Communication in Computational Sociology

Computational sociology models social phenomena using the concepts of emergence and downward causation. However, the theoretical status of these concepts is ambiguous; they suppose too much ontology

A semiosic translation of the term “Bild” in both the Tractatus Logico-Philosophicus and The Philosophical Investigations

Abstract This paper introduces and defends a way to translate Wittgenstein’s Tractatus Logico-Philosophicus and the Philosophical Investigations from a semiotic standpoint. This turn builds on

Programming the Emergence in Morphogenetically Architected Complex Systems

This work argues that among all the self-organized systems studied in the field of Artificial Life, the specificity of MACS essentially lies in the close relation between their emergent properties and functional properties and sees it as good candidates to help design artificial self-architected systems but also harness and redesign living ones.

Toward an Analytic Sociology: Reconciling Structural and Individualistic Explanations of Social Phenomena via a Theory of Embodied Practice

Author(s): Polyakov, Michael | Advisor(s): Bevir, Mark | Abstract: Social theory explanations commonly take one of two forms. Accounts couched in terms of macroscopic entities such as institutions,

An overview of complex behaviour in the groundwater compartment of catchment systems and some implications for modelling and monitoring

An understanding of non-causal relationships between processes in the air, soil and water compartments of the environment is fundamental to sustainable integrated management. This paper provides an

Decisional States

The consequences of grouping histories into states with equivalent optimal decisions in terms of utility, rather than equivalent full distributions of futures are explored.

Towards quantum agents: the superposition state property

The modelling of intelligent complex systems uses the agent paradigm increasingly. However, the problem of decision making with local, incomplete, uncertain, exchanged or observed in asynchronous

A Turing Test for Emergence

In the parlance of complex systems science, the global outcomes arising from broad guidelines on a system’s components, including robustness and adaptivity, are often defined as emergent features.

The Architecture of Complexity

A number of proposals have been advanced in recent years for the development of “general systems theory” which, abstracting from properties peculiar to physical, biological, or social systems, would

Toward a Formalization of Emergence

The author proposes a formal definition of a basic type of emergence using a language-theoretic and grammar systems approach and shows which types of phenomena can be modeled in this sense and what the consequences are for other more complex phenomena.

Methods and Techniques of Complex Systems Science: An Overview

This chapter reviews the main methods and techniques of complex systems science, and discusses the principles of statistical learning and model selection; time series analysis; cellular automata; agent-based models; the evaluation of complex-systems models; information theory; and ways of measuring complexity.

Design and Control of Self-organizing Systems

A methodology to aid engineers in the design and control of complex systems based on the description of systems as self-organizing, which claims that reducing the “friction” of interactions between elements of a system will result in a higher "satisfaction" of the system, i.e. better performance.

Emergence is coupled to scope, not level

It is found that emergent properties are determined by the relationship between the scope of macrostate and microstate descriptions, which establishes a normative definition ofEmergent properties and emergence that makes sense of previous descriptive definitions of emergence.

Emergence: Core ideas and issues

The concept of reduction, which lies at the heart of the emergence idea is explicated, and it is shown how the thesis that emergent properties are irreducible gives a unified account of emergence.

Information-Theoretic Limitations of Formal Systems

An attempt is made to apply information-theoretic computational complexity to meta-mathematics by measuring the difficulty of proving a given set of theorems, in terms of the number of bits of axioms that are assumed, and the size of the proofs needed to deduce the theoremic proofs.

The re-emergence of "emergence": A venerable concept in search of a theory

It will be argued thatEmergent phenomena represent, in effect, a subset of a much larger universe of combined effects in the natural world; there are many different kinds of synergy, but not all synergies represent emergent phenomena.

An information-theoretic primer on complexity, self-organization, and emergence

A set of concepts, together with their possible information-theoretic interpretations, which can be used to facilitate the Complex Systems Science discourse are proposed and it is hoped that the suggested information- theoretic baseline may promote consistent communications among practitioners, and provide new insights into the field.
