Information

Aims, contents and method of the course

In this course, we are going to study two main aspects of networks:

1) Design of some optimal network topologies. We will study several representative problems from this well-established research field using methods of complexity, algorithms and operations research.

2) Analysis of social networks. The growing public excitement by the global ``connectivity'' of the modern society has motivated scientists from multiple scientific disciplines (computer science, applied mathematics, economy and sociology) to develop this new interdisciplinary research field. We will study several graph-theoretical concept of social networks, their complexity and algorithmic approaches for their analysis.

Assessment and permitted materials

- Homework (25%)
- Presentation of a selected topic (15%)
- Oral exam (60%)

At least 60% in total are needed to pass the exam.

Minimum requirements and assessment criteria

This course should help graduate students to:

a) understand information about networks, and
b) develop models and algorithms to design, manage and analyse networks.

Examination topics

1) Graphs.
- Graph Traversal Algorithms. Topological Ordering.
- Dynamic Programming. Shortest Path Algorithms.
- Greedy Algorithms. Minimum Spanning Tree.
- Flow Algorithms.

2) Analysis of social networks
- Graph partitioning (strong and week ties, betweenness measures)
- Networks in their surrounding contexts: homophily, affiliation
- Positive and negative relationships: structural balance, weaker form of structural balance, generalization
- Cascading behavior in networks: diffusion, cascades and clusters. Knowledge, threshold and collective action. The cascade capacity.
- Spreading epidemics in networks: branching process, SIR vs. SIS epidemic model. Analysis of branching process.
