Analyzing the opinion dynamics models discrete & continuous
In this thesis we analyze some of the opinion dynamics in both discrete and continuous cases. In the discrete case, we will find some criteria under which we can say more about the behavior of the dynamics such as convergence of the agents to the same opinion, or consensus. For this purpose, we …

From Opinion Dynamics to Collective Action: How Identity-Based Tolerance Leads to Political Extremism
… surge in political extremism to mechanisms of opinion “homophily” (i.e., like-minded individuals interact more while dissimilar ones might distance) and “assimilation (i.e., interactions homogenize opinions),” which collectively suggest a social world dominated by extreme views. Yet, this view …

An Object-Oriented Parallel Social Simulation Framework
… technique that employs a bottom-up approach for opinion dynamics study. In this work, we develop a social simulation framework based on ABM. The framework supporting multiple features of interest to social scientists and experimenters. The framework supports multiple models where model inputs can …

Census-based population sutonomy for marine tobots: theory and experiments
… The census component is expressed as a nonlinear opinion dynamics model and the multi-objective behavior optimization is accomplished using interval programming. This model can be reduced to recover foundational algorithms in distributed optimization and control, while the full model enables new …

Census-Based Population Autonomy for Marine Robots: Theory and Experiments
… The census component is expressed as a nonlinear opinion dynamics model and the multi-objective behavior optimization is accomplished using interval programming. This model can be reduced to recover foundational algorithms in distributed optimization and control, while the full model enables new …

Modelling, Simulation and Analysis of Deshopping Using A Multi-Agent Based Method
… choice modelling, shop choice, return leniency, opinion dynamics and churn using agent-based modelling and MoHuB framework into focus. It also combines questionnaire survey, ABM modelling and validation interview. The thesis focuses on the use of agent-based modelling and simulation to …

Identifying and assessing coordinated influence campaigns on social networks
… take advantage of social networks to manipulate opinions using artificial accounts, or bots. It is suspected that the 2016 U.S. presidential election was the victim of such social network interference, potentially by foreign actors. Foreign influence bots are also suspected of having attacked …

Efficient algorithms for distributed learning, optimization and belief systems over networks
… we analyze a recently proposed model for opinion dynamics in belief systems with logic constraints. Opinion dynamics are a natural model for a distributed system and serve as an introductory topic for the further study of learning and optimization over networks. We assume there is an …

Stable configurations for population and social dynamics
… models: the Lotka--Volterra model for population dynamics and a tractable polarized opinion social dynamic model. This dissertation contains stability results of the Lotka--Volterra model when induced by a cycle graph food web network. Results such as orbits, chaos and the probability of stability …

Information Propagation Algorithms for Consensus Formation in Decentralized Multi-Agent Systems
… consensus algorithms within control theory and opinion dynamics within computational sociology, and showing how these research areas can be successfully combined to create new and powerful algorithms; and providing an empirical comparison between multiple information propagation algorithms.

Potential-based analysis of social, communication, and distributed networks
… to identify local and global patterns of their dynamics using some novel potential-theoretic techniques. Following the introduction and preliminaries, we focus on analyzing a specific type of distributed algorithm for quantized consensus known as an unbiased quantized algorithm where a set of …

Dynamics and Phenomena in Stateful Multi-Agent Systems
… state, and polarization and discord in models of opinion formation. In Part I, we consider the interplay between learning algorithms and welfare in repeated games with state (also known as stochastic games). In particular, we prove optimal price of anarchy guarantees for natural learning …
