Here is a copy of my book published in 2012 by LAP Lambert Academic Publishing GmbH & Co. KG , almost my doctoral thesis. Click here for some suggested further reading.

Wiener Index of Graphs - Some Graph-Theoretic and Computational Aspects

Subjects of interest

Algorithms, Graph theory, Database theory.

The following students have worked under me in Graph theory/Algorithms   for the Ph.D. degree here in NIT/Trichy:

  • Dr.K.R.Udaya K. Reddy,  An algorithmic study of some distance related problems in graphs (2011) -  click here for synopsis
  • Dr.P.V.Subba Reddy,  A study on r-conditional coloring  and radio-labeling of graphs (2012) -  click here for synopsis

Other activities

I am familiar with ISO9000 and some of the related developments as applied to the software industry. On completing a training course on Internal Auditors of Quality Systems conducted by Quality Management International at Bangalore, I have a certificate dtd. 15th Sept. 1995, no. QMI/IAC/OPH(B)/003.

My students team from NIT-Trichy earned a place in the world finals, held in Tokyo, Japan ,  Banff, Canada and Harbin, China of the 2007, 2008 and 2010 Asociation for Computing Machinery / International Collegiate Programming Contest, popularly known as the olympics of computer programming. Here I am in the cold and here is a final day photograph at Harbin.

For getting started on a doctoral work in Computer Science, here are some quick tips.

Here is one of my ideas to use a university intranet to help Computer Science teaching.
