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 a lecturer in department of Computer Science,
School of Computing (SoC), National University of Singapore (NUS).
I teach various programming/algorithm modules in SoC, NUS (so far 8 different modules),
i.e. CS3233, IT1005, CG1101, CS2281, CS1281, CS2020, IT1006, CS2010, and soon CS3230.

With my brother, Felix Halim, I wrote a book about competitive programming.
You can buy the book via lulu.com.

I have completed my PhD degree. 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 no longer be updated, buy my book instead),
2. my competitive programming lecture notes (these webpages have been removed as they are outdated, buy my book instead),
3. my PhD research project on addressing the `SLS Design and Tuning Problem',
4. my research tool page: SLS Engineering Suite: Viz.
5. my teaching (already outdated as I use NUS IVLE system now).
