Systems-based study of economic processes
Agent-based computational economics (ACE) is the area of computational economics that studies economic processes, including whole economies, as dynamic systems of interacting agents. As such, it falls in the paradigm of complex adaptive systems.

Inorganic nanostructured two-dimensional material
Boron nitride nanomesh is an inorganic nanostructured two-dimensional material, similar to graphene. It was discovered in 2003 at the University of Zurich, Switzerland.

Distinguished surfaces of dynamic trajectories
Lagrangian coherent structures (LCSs) are distinguished surfaces of trajectories in a dynamical system that exert a major influence on nearby trajectories over a time interval of interest.

How humans move within a network
Individual mobility is the study that describes how individual humans move within a network or system. The concept has been studied in a number of fields originating in the study of demographics.

Type of biased random walk on a graph
A maximal entropy random walk (MERW) is a popular type of biased random walk on a graph, in which transition probabilities are chosen accordingly to the principle of maximum entropy, which says that the probability distribution which best represents the current state of knowledge is the one with largest entropy.

Machine learning technique useful for dimensionality reduction
A self-organizing map (SOM) or self-organizing feature map (SOFM) is an unsupervised machine learning technique used to produce a low-dimensional (typically two-dimensional) representation of a higher-dimensional data set while preserving the topological structure of the data.

Network whose links change over time
A temporal network, also known as a time-varying network, is a network whose links are active only at certain points in time. Each link carries information on when it is active, along with other possible characteristics such as a weight.

Branch of physics seeking to explain chaotic dynamical systems in terms of quantum theory
Quantum chaos is a branch of physics focused on how chaotic classical dynamical systems can be described in terms of quantum theory.

Cognitive science approach
Connectionism is an approach to the study of human mental processes and cognition that utilizes mathematical models known as connectionist networks or artificial neural networks. Connectionism has had many "waves" since its beginnings.
Economics › Complexity economics
Strategic network formation defines how and why networks take particular forms. In many networks, the relation between nodes is determined by the choice of the participating players involved, not by an arbitrary rule.

Computerized analytical tool
Microsimulation is the use of computerized analytical tools to perform analysis of activities such as highway traffic flowing through an intersection, financial transactions, or pathogens spreading disease through a population on the granularity level of individuals.

Value of a communication network in terms of its connections
Metcalfe's law states that the financial value or influence of a telecommunications network is proportional to the square of the number of connected users of the system (n2).
