Research work
Matchings in graphs -- Fall '10
Supervisor : Prof. K. Muralikrishnan, NIT Calicut
Currently working on Edmond's blossom algorithm and determining the complexity of matching problem (currently known to be in RNC).
Assigned the complexity class of decision version of maximum matching - logspace (L).
Mechanisms for Prediction Markets -- Summer '10
Supervisor : Prof. Y. Narahari, IISc Bangalore
Worked on different mechanisms for prediction markets and proposed a better heuristic for the same.
Placement Algorithm for Virtual Machines -- Fall '10
Supervisor : Prof. Umesh Bellur, IIT Bombay
Worked on the placement algorithm; for a set of input configurations of VMs on Physical Machines (a multi-dimensional bin packing problem)
Character Recognition using Artificial Neural Networks -- Fall '10
Supervisor : Prof. S Kumaravel, NIT Calicut
Worked on recognizing characters using the feed-forward back-propagation artificial neural network. Also performed comparison studies for different configurations.
Cloud Computing for Mobile World -- Fall '10
Supervisor : Prof. Madhu Kumar S.D., NIT Calicut
A literature survey on the current status of Mobile Cloud Computing (MCC) and analysed it's shortcomings.
