I have received the task to make a social graph, where, with one user in the center, it shows the connections he has. But before we can reach that, our focus is how we can determine the shortest path between 2 users. I found some algorithm to do it, but it seems that it takes a lot of time, and because it's about social links, we are loo...

I have a tree structure of interconnected nodes of various types. Each node keeps track of which nodes it is connected to. In this structure I need to find the longest unconnected chain or path of same type nodes. I've read up on graphs and breadth/depth first searches but these don't quite yield the results I need.

In other words, the maximum images that be can be attached to my image type "IMAGE", is 1. My problem is, that users must be able to upload several images at once. So, I need one of the following: A way to create seve...
I came across some javascript at work today that used jQuery to fetch two elements. It then used elem.nodeIndex to determine the position in the elements parent for each element. Nothing is setting this property anywhere and I do now see a reference to it in the msdn, mdc, or anywhere else. I stepped through this javascript in FireFox ...

Is there an algorithm that will, if given two nodes on a graph, find a route between them that takes the specified number of hops? Any node can be connected to any other. The points at the moment are located in 2D space, so I'm not sure if a graph is the best approach. ...
