Why World of SEVEN (7)?

7 in English is "SEVEN" and my name is "STEVEN", very similar, only 1 edit distance!,
7 reflect completeness,
7 is a perfect number,
7 is a prime,
7 is said to be lucky number, and many others...

Who am I?

I am an instructor in department of Computer Science, School of Computing (SoC), National University of Singapore (NUS).
I teach IT1005 - Introduction to Programming with MATLAB & CG1101 - Programming Methodology in Semester 1, 2009-2010.

I am also waiting for my PhD defense. My main PhD research is to investigate human-computer collaboration (in form of FLST visualization plus automated black-box tuning) to address Stochastic Local Search `Design and Tuning Problem' (SLS DTP). So far, I have co-authored several scientific articles on international journals and conferences around this topic. This SLS DTP is a high level problem suffered by the algorithm designer while they try to create a good performing SLS algorithms (a.k.a. metaheuristics) for attacking the underlying NP-Hard Combinatorial (Optimization) Problems. I have designed an SLS engineering suite Viz that incorporates my ideas above (see picture on the right) to help me address this SLS DTP.

What is this website about?

The content of this website are:
1. my hints for doing problem solving in a famous UVa online judge (this section will be updated this year, but not often),
2. my competitive programming lecture notes (will be updated after this semester is over ~ May 2009?),
3. my ongoing PhD research project on addressing the `SLS Design and Tuning Problem',
4. my research tool page: SLS Engineering Suite: Viz.
5. my teaching (always updated every semester for my students).

All other materials that are my personal view and not related to School of Computing, National University of Singapore, are hosted in my personal website in googlepages (this one is not complete yet). Please feel free to browse this and my personal website.
