• Fault tolerance techniques for emerging nanoelectronic circuits (May-July 2006)
  • The optimal reconfiguration of nanoelectronic mesh is known to be NP-complete. An efficient near optimal reconfiguration algorithm for the problem was proposed. The algorithm offers an average switch density improvement of 50% to100 % to most recently published techniques. The simulation was done in C++ on Linux platform.
  • Extensive analysis was done to compare the results of the proposed algorithm and the most recently published techniques.
  • A research proposal for further research in emerging nanoelectronic circuits was submitted to EPSRC, UK.

• On the reliability of mesh and ring networks (May-December 2005)
  • Two dimensional mesh network of processing elements was considered and the reconfiguration capability of the network was thoroughly analyzed for various link configurations. In case of bidirectional links, optimal reconfiguration was found to be NP-complete, for other link configurations efficient algorithms were found.
  • Some bounds on the reconfiguration capability of Forward Loop Forward Hop (FLFH) networks were found. Efficient reconfiguration strategy for generalized FLFH networks was found.

• Divide and Conquer Strategy for Minimum Spanning Tree of Planar Graphs (May-July 2005)
  • Different divide and Conquer approaches were tried for planar graphs. The graph was initially divided by the famous planar separator into parts before finding their individual MST’s. Various strategies to merge the resulting MST’s were tried, but the resulting time complexities were unfavorable.
