Why World of SEVEN (7)?

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

Who am I?

I am a full-time teaching assistant in department of Computer Science, School of Computing (SoC), National University of Singapore (NUS). I teach CS1102 in Semester 1, 2008-2009.

I am also a final year part-time PhD student (graduating soon??). 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.

My Personal Vision

"To invent something new and useful for humanity. To pass the existing knowledge to younger generations. To God be the Glory."

It has been my interest to play around with new things. I am also the type of person who do not like to be trapped in the routines of daily activities like other people normally do. I am now in my last year (hopefully) of PhD candidature and trying my best to finish this PhD programme. I will make the most of my candidature to explore new things, invent new and useful things... And whatever the results that I (have/will) found... To God be the Glory. I am also interested in teaching (especially teaching algorithm/programming). Thus, from these two main interests, it is very likely I will pursue academic path (e.g. faculty member of university) in the future.

My Religious Belief

I believe in God, the creator of the universe.
I believe His son, Jesus has died for my sin on the cross.
I believe the Holy Spirit is guiding me and all Christians until the second coming of Christ.

What is this website about?

The major content of this personal website is about problem solving (no longer updated) using proper data structures, good algorithms, and computer programming (will be updated once and then freezed). I also have a section about my ongoing research project which attempts to address the `SLS Design and Tuning Problem', another section about my teaching, a collection of several free software that I built in the past, and another section which contains my thoughts and my writings regarding Christianity or other interesting issues.

Please feel free to browse this website. You can always send me your feedback about this website.
I really appreciate any feedback from you.

Btw, for anyone out there who has the same interest like me, you can contact me for more discussion =). Note: sometimes I am too busy to respond to e-mail correspondence, my apology in advance for that.
