The basic general strategy is: Replace a difficult problem with an easier one that has the same solution (or closely related solution) . In other words, transform the representation of your difficult problem into a different representation that is easier to solve and producing solution that is a solution...

As promised in my earlier post , here I'd like to talk about Amdahl's Law , thru which you'll get the formal idea that speed up by parallelism only really works for certain kind of problems. Problems which algorithms to solve have small serial fractions. My goal with this post is to give...

Let say it takes 6 minutes to do a computation on a set of data in a single processor. Then you have 3 processors altogether. Would your task finish in 2 minutes (6 divided by 3)? NO IT WON'T! Why? Because your algorithm is a sequential algorithm. Even if with 100 processors your computation would...

Last time I talked about the several kinds of parallelism , now I'd like to talk about the methodology we can use in designing a parallel algorithms, The Foster's Methodology. First, let's define first a Unit of Computation and call it a Task. A Parallel Computation is merely a set of Tasks...

If you have checked out my paper about the using of Feed-Forward Backpropagation Neural Networks , here's another approach that I used. It is called the Probabilistic Neural Networks . This approach can forecast the onset of Diabetes Mellitus with 100% accuracy . Compared to the Feed-Forward Backpropagation...

I'd like to sparks and encourage scientific culture in our community. So, I created a new folder called " papers " in our geeks site download section. Here, you can upload (and download) papers, writings that have a more academia style (for more relaxed content, you still can find them...

In addition to .NET and programming in general, I will also write about the area of my upcoming thesis: Scientific Computing. I will start easy. As always. First, by defining what is Scientific Computing. Traditionally, it is called Numerical Analysis . It is concerned with the design and analysis of...

Cara menghaluskan gunung di dunia 3D. Jika berkutat dengan XAML dan WPF, kita tentu tahu bahwa segala model 3D tersusun atas segitiga. Jadi mau membuat bentuk apapun, segalanya tersusun atas segitiga. Dari segitiga-segitiga itulah terbentuk berbagai macam model, mulai dari tank, mobil, pesawat, robot...
