Phylogenetic Recapitulation in the Ontogeny of Artificial Neural Networks (1993)
Stefano Nolfi, Domenico Parisi
The order in which anatomical characteristics develop in an individual from conception to maturity (ontogeny) may repeat the evolutionary history of the individual's species (phylogeny)....
Growing neural networks (1991)
Stefano Nolfi, Stefano Nolfi, Domenico Parisi, Domenico Parisi
Growing neural networks are networks which are constructed by executing genetic instructions contained in a genotype. These instructions and their products interacts non-linearly to eventually...

Learning and Evolution in Neural Networks (1990)
Stefano Nolfi, Stefano Nolfi, Jeffrey L. Elman, Jeffrey L. Elman, Domenico Parisi, Domenico Parisi
The paper describes simulations on populations of neural networks that both evolve at the population level and learn at the individual level. Unlike other simulations, the evolutionary task (finding...
Learning and Evolution in Neural Networks (1990)
Stefano Nolfi, Istituto Di Psicologia, Jeffrey L. Elman, Domenico Parisi
In this report we present the results of a series of simulations in which neural networks undergo change as a result of two forces: learning during the "lifetime" of a network, and...

Cultural Transmission Between and Within Generations
Alberto Acerbi, Domenico Parisi
We describe some simulations that compare cultural transmission between and within generations (inter-generational vs intra-generational transmission) in populations of embodied agents controlled by...
Individual Versus Social Survival Strategies
Federico Cecconi, Domenico Parisi
The paper introduces the concepts of individual survival strategies (ISS) and social survival strategies (SSS) and presents three sets of simulations of a particular type of SSS: the Central Store...
Defining and identifying communities in networks
Radicchi, Filippo, Castellano, Claudio, Cecconi, Federico, Loreto, Vittorio, Parisi, Domenico
The investigation of community structures in networks is an important issue in many domains and disciplines. This problem is relevant for social tasks (objective analysis of relationships on the...

Groups of Agents with a Leader
Onofrio Gigliotta, Orazio Miglino, Domenico Parisi
We describe simulations of groups of agents that have to reach a target in a two dimensional environment, the performance criterion being the time taken by the last agent to reach the target. If the...
Exiting TANF: Individual and Local Factors and Their Differential Influence Across Racial Groups
Domenico Parisi, Diane K. McLaughlin, Steven Michael Grice, Michael Taquino
We ask whether individual and local factors known to influence reliance on welfare continue to be important under the TANF program, and if such factors differentially affect exit from TANF for...
Gender Role Ideologies and Marriage Promotion: State Policy Choices and Suggestions for Improvement
Deborah A. Harris, Domenico Parisi
The 1996 Personal Responsibility and Work Opportunities Reconciliation Act (PRWORA) lists marriage as one of the major strategies for reducing welfare dependency among clients of the Temporary...
Neural Networks in an Artificial Life Perspective
Stefano Nolfi, Domenico Parisi
. In the last few years several researchers within the Artificial Life and Mobile Robotics community used Artificial Neural Networks. Explicitly viewing Neural Networks in an Artificial Life...
Race and the micro-scale spatial concentration of poverty
Daniel T. Lichter, Domenico Parisi, Michael C. Taquino, Brian Beaulieu
This paper uses block-group data from the US decennial censuses to document changes in concentrated poverty. It provides several substantive and methodological lessons. First, the majority of poor...
