Optimality of delayed reward attainment under uncertainty
Chuwei Wang, Alexander Vladimirsky, Anastasia Bizyaeva
Decision making under uncertainty requires balancing the value of additional information against the cost of delaying the decision until that information becomes available. This ch…
Constraint-Induced Redistribution of Social Influence in Nonlinear Opinion Dynamics
Vishnudatta Thota, Anastasia Bizyaeva
We study how intrinsic hard constraints on the decision dynamics of social agents shape collective decisions on multiple alternatives in a heterogeneous group. Such constraints may…
Sustained oscillations in multi-topic belief dynamics over signed networks
Anastasia Bizyaeva, Alessio Franci, Naomi Ehrich Leonard
We study the dynamics of belief formation on multiple interconnected topics in networks of agents with a shared belief system. We establish sufficient conditions and necessary cond…
Switching transformations for decentralized control of opinion patterns in signed networks: application to dynamic task allocation
Anastasia Bizyaeva, Giovanna Amorim, Maria Santos +2
We propose a new decentralized design method to control opinion patterns on signed networks of agents making decisions about two options and to switch the network from any opinion…
Control of Agreement and Disagreement Cascades with Distributed Inputs
Anastasia Bizyaeva, Timothy Sorochkin, Alessio Franci +1
For a group of autonomous communicating agents, the ability to distinguish a meaningful input from disturbance, and come to collective agreement or disagreement in response to that…
Patterns of Nonlinear Opinion Formation on Networks
Anastasia Bizyaeva, Ayanna Matthews, Alessio Franci +1
When communicating agents form opinions about a set of possible options, agreement and disagreement are both possible outcomes. Depending on the context, either can be desirable or…
Nonlinear Opinion Dynamics with Tunable Sensitivity
Anastasia Bizyaeva, Alessio Franci, Naomi Ehrich Leonard
We propose a continuous-time multi-option nonlinear generalization of classical linear weighted-average opinion dynamics. Nonlinearity is introduced by saturating opinion exchanges…
