Title: Voter model dynamics on complex networks
Supervisor:
Research Area: Complex Systems and Networks
Description:

Imitation is one of the basic mechanisms through which consensus can emerge in a population of interacting agents. The voter model is a minimal mechanistic model of social imitation which presents interesting dynamical properties.

In this project the student will simulate the voter model in a variety of synthetic and real-world networks, will reproduce the analytic calculations to estimate the order parameter of the model in the thermodynamic limit and the typical time to reach the absorbing state in finite graphs, and will compare the numerics with the analytic predictions.

The student is expected to possess a well-balanced mixture of analytic and computational skills (knowledge of C/C++/Python would be preferred, Matlab/Octave might be sufficient).
