Abbreviations
- Abduction:
-
also called inference to the best explanation, abduction is a method of reasoning in which one looks for the hypothesis that would best explain the relevant evidence.
- Agents:
-
entities of a model that (i) are perceived as a unit from the outside, (ii) have the ability to act, and possibly to react to external stimuli and interact with the environment and other agents.
- Agent-based computational economics (ACE):
-
is the computational study of economic processes modeled as dynamic systems of interacting agent.
- Agent-based models (ABM):
-
are models where (i) there is a multitude of objects that interact with each other and with the environment; (ii) the objects are autonomous, i. e. there is no central, or top-down control over their behavior; and (iii) the outcome of their interaction is numerically computed.
- Complexity:
-
there are more than 45 existing definitions of complexity (Seth Lloyd, as reported on p. 303 in [97]). However, they can be grouped in just two broad classes: a computational view and a descriptive view. Computational (or algorithmic) complexity is a measure of the amount of information necessary to compute a system; descriptive complexity refers to the amount of information necessary to describe a system. We refer to this second view, and define complex systems as systems characterized by emergent properties (see emergence).
- Deduction:
-
the logical derivation of conclusions from given premises.
- Economics:
-
is the science about the intended and unintended consequences of individual actions, in an environment characterized by scarce resources that both requires and forces to interaction.
- Emergence:
-
the spontaneous formation of self‐organized structures at different layers of a hierarchical system configuration.
- Evolution:
-
in biology, is a change in the inherited traits of a population from one generation to the next. In social sciences it is intended as an endogenous change over time in the behavior of the population, originated by competitive pressure and/or learning.
- Heterogeneity:
-
non‐degenerate distribution of characteristics in a population of agents.
- Induction:
-
the intuition of general patterns from the observation of statistical regularities.
- Interaction:
-
a situation when the actions or the supposed actions of one agent may affect those of other agents within a reference group.
- Out-of‐equilibrium:
-
a situation when the behavior of a system, in terms of individual strategies or aggregate outcomes, is not stable.
