Research Topic Description, including Problem Statement:

  • Complex networks are widely used to represent a variety of scenarios: from social networks and terrorist cell structures to airline routing, as well as being used in image processing and biology. They can be used to represent any system and harness methods to identify control points, communities and key players. The structure of the network is key to its function. Often, the analysis of these networks is undertaken manually however the scale and breadth of these networks in all scenarios are vastly increasing and becoming more complex. This leads to very large networks which are too large for manual analysis and increasingly reaching limits on computational processing. The size of these networks is expected to continue to increase exponentially.
  • For several months, limited research has been undertaken to identify ways of overcoming this problem. There are a limited number of algorithms available to process such large datasets, and most require setting a pre-determined number of partitions.

Some algorithms found include:

  • Overview of algorithms:


  • Graph partitioning based on spreading the load across a pre-defined number of computers:


  • Partitioning based on structure of graph:


  • Open source datasets of complex networks are available for use including:




Example Approaches:

  • A scalable method for partitioning complex network graphs into an optimal number of parts is required. This could be approached by:
    • Research into available algorithms and assessment of suitability for implementation and/or adaption. Any methods should be considered against
      • Scalability
      • Consideration of preserving key network structure
      • Optimization of number of partitions.
    • Consideration of data flow techniques as emerging methods for understanding the underlying structure of networks.
    • Implementation of one or more methods for assessing against open source data
    • Updating of method dependent on test results.
    • Technical partnering will be provided.
