Hi i've been working on a piece of homework we're I've been asked to implement a 2d grid in opengl and extend Dijkstra's algorithm to A star, so far i've been able to get the 2d grid running with Dijkstra's algorithm with not too many problems but my current extenstion to A star has me scratching my head, i'm just wondering if I'm approaching it all wrong or if I'm going in the right direction with just a few careless mistakes. So my main question is can you see what I am doing wrong? Am I calculating the Manhatten distance … +0 okay so i have this program that is basically like moving the sides to a 2 dimensional rubiks cube. for example 111 222 333 is a 3X3 two dimensional array and when coordinate (0, 1, 2 being 1, 2, 3) 1, 1 (meaning in our number system as 2, 2) would like to be moved up based on the user input, then the numbers in that array move as follows 121 232 313 and so on and so forth now my problem is that i can figure this out, eventually but the way im doing it is faaaar to tedious, … +0 I have performed heuristic evaluation on the following web site "http://www.ghanaairports.com.gh/" and identified a couple of problems. Am supposed to submit this as part of my assignment and want to validate my findings and improve my findings should there be a criteria am missing. Id be very grateful if respondents can, from their own point of view, using Nielsen heuristics([url]http://www.useit.com/papers/heuristic/heuristic_list.html[/url]) perform a heuristic evaluation on this website ([url]http://www.ghanaairports.com.gh/[/url]) and identify any problems by classifying them in the following categories; [LIST] 1. Interface Design (layout, typography, white spaces, images, colour schemes. 2. Navigation 3. Information Architecture 4. Functionality 5. Languages It … +0 News Story Kaspersky wins heuristic analysis technology patent Kaspersky Lab has successfully [URL="http://www.itpro.co.uk/blogs/daveyw/2009/02/23/kaspersky-patents-malware-removal/"]patented yet another bit[/URL] of security technology. This time it is a new heuristic analysis technology which allows security ratings to be assigned to software based entirely upon behaviour patterns during emulation. Is this something to get excited about? Well, yes, if you look beyond the marketing spin and focus on what Kaspersky is actually doing here. The point being that with existing methods there are no 100 percent guarantees that new malicious programs can be detected, a typical chicken and egg situation which would require new technologies to detect and block potential new threats to … +0

The End.
