Collapse and rescue of cooperation in evolving dynamic networks
Nature Communications, 2018 The evolution of cooperation depends on social structure, which may evolve in response. Here, Akçay models coevolution between cooperation and social network formation strategies, showing that coevolutionary feedbacks lead cooperation to collapse unless ...

HedN Game, a Relational Framework for Network Based Cooperation [PDF]
This paper proposes a new framework for cooperative games based on mathematical relations. Here cooperation is defined as a supportive partnerships represented by a directed network between players (aka hedonic relation). We examine in a specific context,

Homophilic wiring principles underpin neuronal network topology in vitro
eLifeEconomic efficiency has been a popular explanation for how networks self-organize within the developing nervous system. However, the precise nature of the economic negotiations governing this putative organizational principle remains unclear.

Predicting reservoir quality in sandstones through neural modeling
Vetor, 2013 Due to limited understanding of the details of many diagenetic processes, mathematical models become a very useful tool to predict reservoir quality prior to drilling.

Efficiency of network structures: The needle in the haystack [PDF]
The modelling of networks formation has recently became the object of an increasing interest in economics. One of the important issues raised in this literature is the one of networks efficiency.

Coordination and Evolutionary Network Formation with Asymmetric Link Costs: Part One [PDF]
We analyze a dynamic implication of an evolutionary process in a population where both actions and network structures changes over time. At every period, a coordination game is played by players who are linked with each other.

An Agent-based Route Choice Model [PDF]
Travel demand emerges from individual decisions. These decisions, depending on individual objectives, preferences, experiences and spatial knowledge about travel, are both heterogeneous and evolutionary. Research emerging from fields such as road pricing

Inference in Semiparametric Formation Models for Directed Networks
Journal of Business & Economic StatisticsWe propose a semiparametric model for dyadic link formations in directed networks. The model contains a set of degree parameters that measure different effects of popularity or outgoingness across nodes, a regression parameter vector that reflects the homophily effect resulting from the nodal attributes or pairwise covariates associated with edges, and

Explaining nineteenth-century bilateralism: economic and political determinants of the Cobden-Chevalier network [PDF]
This study investigates the empirical determinants of the treaty network of the 1860s and 1870s. It makes use of three central theories about the determinants of PTA formation, considering economic fundamentals from neoclassical and ‘new’ trade theory ...

Application of attention mechanism-based LSTM neural network in stratigraphy identification
Results in EngineeringThis paper proposes a lithology recognition system based on a Long Short-Term Memory (LSTM) neural network, which incorporates multi-head masked attention mechanisms and the Transformer architecture.
