Gabow Strongly Connected Component Algorithm
Posted by Nathaniel Calloway on May 8th, 2008



Anyone out there know of an example of an implementation of Gabow's
SCC algorithm out there on the interwebs? (Note: I'm *not* looking for
Gabow's various graph matching algorithms).

The language doesn't matter

I got 511 hits with this:
http://www.google.com/search?hl=en&q...+scc+algorithm

Have you already explored the net yourself?

Yes.

Did you bother to click on anything in that search? Click on the
first 50 or so, and you'll get the idea why I asked here.

But that's beside the point. Even if my question was easily answered
by a google search, if you don't want to help, just delete.

I found several.

Here is code in python. Have a nice day.

Out of curiosity, I decided to see how far down that was on your
search. Wow, 87th! You really didn't have to go to that much work

Snarkiness aside, thanks.

Sedgewick has implementations of Kosaraju's, Tarjan's and Gabow's
linear time algorithms. You can download the code from his site (but
using it commercially requires permission).
I have has graph algorithm book for C, and it is on pages 197-206.
The algorithm is also available in C++ and Java.

HTH.

Since I was looking for code, I did not bother with any of the pdf's. Took
me less than 2 minutes.

It's actually quite an interesting problem and I am glad you brought it up.
