Journal ArticleDOI
Adaptive Competition, Market Efficiency, and Phase Transitions
TL;DR: This work analyzes a simple model that incorporates fundamental features of social and biological systems that simultaneously and adaptively compete for limited resources, thereby altering their environment.
Journal ArticleDOI
Stationarity and nonstationarity in time series analysis
Radu Manuca,Robert Savit +1 more
TL;DR: A new class of methods to test, model and describe nonstationary processes that generalize the dynamical description of autonomous systems to the case of nonautonomous systems for which the driving force is recurrent are introduced.
Journal ArticleDOI
The structure of adaptive competition in minority games
TL;DR: It is shown that the best individual agent performance in the two different phases is achieved by sets of strategies with markedly different characteristics, and a mean-field-like model of the game is proposed which is most accurate in the maladaptive, efficient phase.

Adaptive Competition, Market Efficiency, Phase Transitions and Spin-Glasses
TL;DR: A simple model of adaptive competition which captures essential features of a variety of adaptive competitive systems in the social and biological sciences is analyzed, which has some features reminiscent of a spin-glass.
Journal ArticleDOI
Model misspecification tests, model building and predictability in complex systems
Radu Manuca,Robert Savit +1 more
TL;DR: In this paper, the authors show that using functions of simple variables, such as time lags, as directions in reconstruction spaces for complicated time series can improve model building and predictability of the time series.
