Level: Postgraduate
Faculty/School: School of Information Technologies
Unit Coordinator/s: Seneviratne, Suranga

Versions for this Unit:
Campus: Camperdown/Darlington

Brief Handbook Description: The growing connected-ness of modern society translates into simplifying global communication and accelerating spread of news, information and epidemics. The focus of this unit is on the key concepts to address the challenges induced by the recent scale shift of complex networks. In particular, the course will present how scalable solutions exploiting graph theory, sociology and probability tackle the problems of communicating (routing, diffusing, aggregating) in dynamic and social networks.
Assumed Knowledge: Algorithmic skills (as expected from any IT graduate). Basic probability knowledge.

Attributes listed here represent the key course goals (see Course Map tab) designated for this unit. The list below describes how these attributes are developed through practice in the unit. See Learning Outcomes and Assessment tabs for details of how these attributes are assessed.

Attribute Development Method Attribute Developed
The task and assignment in the unit give students opportunities to identify, integrate and synthesise knowledge on networks and algorithms to solve problems under constraints.
Assignments will give students the opportunity to develop programming skills by writing social or analytical algorithms and to develop research skills by allowing them to explore and criticise research articles in sociology, economy or graph theory and their applications to information technologies.
Engineering/IT Specialisation (Level 4)
Students will be explained through illustrative examples and real-case situations observable by themselves the impact of these properties in the exchange of information in the world wide web or in social networks. The students will learn and apply thoroughly the different properties inherent to graph theory and sociology that impact the performance and behavior of communicating activities. Such properties made applicable to other situations and examples will help the students develop skills to transpose these properties in other contexts, analyse theoretically their impact, and draw some conclusions on the resulting performance and behavior of various complex communication networks. Maths/Science Methods and Tools (Level 4)
The students will be given various complex problems that they will need to solve, requiring research of the appropriate background information and research bibliography using resources such as the university library and the Internet. Students will also be required to understand different types of information and its representation and use in complex networks, and will be exposed to standards that ensure the consistency and quality of such information. Information Seeking (Level 4)

For explanation of attributes and levels see Engineering & IT Graduate Outcomes Table 2018.

Learning outcomes are the key abilities and knowledge that will be assessed in this unit. They are listed according to the course goal supported by each. See Assessment Tab for details how each outcome is assessed.

5. Students understand the asymptotic complexity and accuracy of graph algorithms.
6. Students know the stochastic methods necessary to evaluate the convergence of various algorithms.
7. Students recognise probabilistic solutions to problems that have no deterministic solutions and apply them thoroughly.

8. Students have skills to compare experimentally and theoretically the adequacy of different probabilistic solutions.
9. Students are familiar with various types of network models in different contexts like computer science, society or markets
10. Students understand the fundamental structures, dynamics and resource distribution in such models.

Grading:
Grade Type Description
Standards Based Assessment Final grades in this unit are awarded at levels of HD for High Distinction, DI (previously D) for Distinction, CR for Credit, PS (previously P) for Pass and FA (previously F) for Fail as defined by University of Sydney Assessment Policy. Details of the Assessment Policy are available on the Policies website at http://sydney.edu.au/policies . Standards for grades in individual assessment tasks and the summative method for obtaining a final mark in the unit will be set out in a marking guide supplied by the unit coordinator.
Minimum Pass Requirement It is a policy of the School of Information Technologies that in order to pass this unit, a student must achieve at least 40% in the written examination. For subjects without a final exam, the 40% minimum requirement applies to the corresponding major assessment component specified by the lecturer. A student must also achieve an overall final mark of 50 or more. Any student not meeting these requirements may be given a maximum final mark of no more than 45 regardless of their average.
Policies & Procedures: IMPORTANT: School policy relating to Academic Dishonesty and Plagiarism.

In assessing a piece of submitted work, the School of IT may reproduce it entirely, may provide a copy to another member of faculty, and/or to an external plagiarism checking service or in-house computer program and may also maintain a copy of the assignment for future checking purposes and/or allow an external service to do so.

Other policies
