Hey, I have a problem - I'm to write how can a genetic algorithm document clustering program I wrote be combined (and benefit from that) with a "standard search engine". What could be considered a "standard search engine", in the given context?

First I want to say thank you to those who help me in my project last year espicially to sir ardav and to this site itself. now I'm in my (hopefully) last year of my college and now I'm thinking of "Online Establishment Finder System" as my final project. But …

I know .NET is a Microsoft framework. I currently use Visual Studio 2008 for C++ programming in school. Am I using .NET? What is .NET? More specifically, is C++ a .NET framework by default? Does it just relate to the class libraries?

I am currently working on kind of multi-graph structure. The thing is that two graphs are needed for my application which span the same vertices but with two distinct set of edges (i.e., a multi-graph). The first graph is a binary search tree, while the second graph must be general …

Hello! I'm searching for a UML tool that can comprehensively 3D visualize a big (class) diagram. Something like a crossover between Google Sketchup and a proper modelling tool - or a tool which uses an XMI export as a base for its 3D visualization. Ideally it would also provide an …

I was recently toying with an idea from my education in computer science, namely that any deterministic algorithm can be expressed with just two control structures: a loop containing a switch. I never doubted it. From a certain point of view, that's what programs look like to the silicon of …

Please can you help me to calc the complexity of this algorithm it may looks easy but i am new to all that int f=1; int x=2; for (int i = 1; i <= n; i*=2) for (int j = 1; j <= i * i; j++) if (j % …

So this is mainly a Design/Clean Coding sort of question, I know I've read something about this previously but I can't find it, I believe it's in one of my reference books on C/C++ so it wouldn't likely be useful to my predicament. This question includes a lot of Java …

Why is it that a perceptron or a single layered neural network can't solve the XOR problem, or problems that are linearly inseparable. Before someone tells me to use google, I have. All the neural network guides that are online or in books are so overly complicated with masses of …

Here is an amazing article. Peter Norvig does not let small detail, that the language was never implemented in it's time, disturb his debugging the code written without implementation, but single handedly implements it with Python parser. Frustration warning, this is frustratingly amazing stuff: [Prescient but Not Perfect: A Look …
