HTML, or Hyper-Text Markup Language, is the backbone of most WebPages. Web Browsers interpret HTML commands to display Web Pages. If you are completely new to web development, we suggest you take a moment or two and start with the Beginner Tutorial to introduce some basic concepts needed in other web development topics. You need to be comfortable with HTML markup before tackling the scripting languages like Javascript and PHP.

Python is an extremely powerful scripting/programming language where many concepts allow beginnners and novices to get up to speed quickly. Python is used in many professional applications and can be interfaced with C, Lisp and many other programming languages.

Website Design Rules contains some general guidelines and common-sense suggestions to keep your websites in line with usual and customary accepted practices.

Excellent Tech Support

Breadth-First Search is a search strategy where nodes are expanded at a given depth in the search tree before any nodes at the next level are expanded. A C++ program utilizing Breadth-First strategy is given.

Depth-First Search is a search strategy where the deepest node in the current frontier of the search tree is expanded first. A C++ program utilizing Depth-First strategy is given.

A* Search is a search strategy used to minimize the cost(time) of reaching the goal. Heuristics are used to eliminate expensive paths.

Topics discussed assume minimal computer experience, attempts are made to thoroughly explain items, so that anyone with a desire to learn the material can do so. Screenshots will be available to help users understand the mechanics of the material being presented.

We try to eliminate errors in the documentation as best we can, although some may still remain. If you have any questions or better yet, suggestions, you may contact us through email, or the blog (once it is set up). We will respond as time permits. Unless otherwise stated, you may copy code or images and save them to your server, but we ask that you do not hot link to our site as this consumes too much server bandwidth from our ISP.
