[Cartoweb-users] Shortest Path

[sames pit]

Hi, 
I have been using Cartoweb on my server. I have large data of a city in my Postgresql database. I am using boost library when i am requiring to find the shortest path. The reference site i have been using is http://chris.narx.net/2005/12/14/build-your-own-routing-solution/.

I want to plot K shortest paths for some K. Can u help me by providing links to resources giving K shortest path algorithms . 

Thanking you, 
sames
