Jarvis’ March

In computational geometry, Jarvis’ march or gift wrapping algorithm is used to compute the convex hull of a given set of points. The algorithm has broad range of applications in mathematics and computer science practically in pattern recognition, image processing, statistics, geographic information system (GIS) and game theory. Convex hull or convex envelope of a…

Z — Axiomatic Definition

Z (pronounced as zed) is a formal specification language which uses mathematical text to describe computing systems. Unlike some informal methods such as Data Flow Diagram, which only describes the structure of the computing systems; and State Transition Diagram, which only describes the finite state model of the computing systems; Z is a model-based notation…

Z with LyX

Z (pronounced as zed) is a formal specification language used to describe and model complex computing system. I’ve been reading about it for some time and I am much fascinated by its abstraction and elegance. I’m really keen to practice Z but before I can adopt the notation in my work, I need to make sure…

Nothingness

I tried to blog nothing at all this month, but turns out I have something to write. Behold the mighty addiction of blogging. I look at blogging at another way other than getting my rants across the world. But, this is not the purpose of this post. Nope, I am not going to write about…

Algorithmic art

Jean-Pierre Hébert, a 68-year-old French artist, is an algorist. This is a name, proposed by Jean himself, for artists who create arts using unique computer algorithms. Apple featured Jean and his works in May 2008. You can read about him here so I am not going to repeating writing about him and his works. When…

My new blog title

As you can see, I have a new blog title “Pragmatic Revelations”. I also like my old title “The Eccentric Logic of An Eclectic Mind”. Actually, I am a little too sentiment to change to the new blog title and not using the old one. When M emailed me she preferred the old title, I…

Computational Mathematics

I am not a mathematician but I realize and love the beauty of mathematics. Our life and surroundings are all driven and governed by mathematics. How? Everything in this universe can be modeled using mathematics equation. When we move our fingers, when coins are dropped, when we kick, when two cars collide, and everything. Nothing…
