How can we detect if a directed graph is cyclic? I thought using breadth first search, but I'm not sure. Any ideas?

I have a database with Performance counter data and i would like to show this on a ASP.net page but the thing is i don't want to use Flash based charting solution or a Javascript based solution i would like to just generate images and use those I want the images to be like those of RRD or MRTG.
I'm…

I am currently doing some experimental work and I have a lot of data to trawl though. I use Gnumeric, and it's very good, but often I feel there has to be something better.
Ideally I would like the maximum number of features with a minimal learning curve, but really I'd just like to know if there…

I've done some basic 1 D integration, but i can't wrap my head around things and apply it to my graph layout.
So, consider the picture below:
if i drag the red node to the right, i'm forcing his position to my mouse position
the other nodes will "follow" him, but how ?
For Verlet, to compute the…

I understand BFS, and DFS, but for the life of me cannot figure out the difference between iterative deepening and BFS. Apparently Iterative deepening has the same memory usage as DFS, but I am unable to see how this is possible, as it just keeps expanding like BFS.
If anyone can clarify that would…

First of all, thank you for looking at this question.
For a school assignment we're supposed to create a BFS algorithm and use it to do various things. One of these things is that we're supposed to find all of the paths between the root and the goal nodes of a graph. I have no idea how to do…

We are given an array of integers where all elements are between 0-9. have to start from the 1st position and reach end in minimum no of moves such that we can from an index i move 1 position back and forward i.e i-1 and i+1 and jump to any index having the same value as index i.
Time Limit : 1 second

Let's say you wanted to implement a breadth-first search of a binary tree recursively. How would you go about it?
Is it possible using only the call-stack as auxiliary storage?
