Re: [Boost-users] [BGL] k-shortest path

Hi Jeremy and others, FYI, I implemented the Yen algorithm: https://svn.boost.org/trac/boost/ticket/11838 Best, Irek On 11.10.2015 08:36, Jeremy Murphy wrote:

Hi Irek,

I need to find k-shortest paths, but there is no such algorithm in BGL. I can get edge-disjoint k-shortest paths with a max-flow algorithm, but I don't need the k-shortest path to be edge-disjoint -- that's too strict for me.

I would appreciate it if someone could share an implementation of the Yen or Eppstein algorithms using BGL. I found some implementations on the Internet, but they don't use BGL.

As you may already know, Eppstein and Yen algorithms are different with respect to loops, so be sure which one you need.

You may also wish to consider K*: http://www.sciencedirect.com/science/article/pii/S0004370211000865

You don't have to be a BGL guru to implement algorithms that work on BGL graphs: have you tried giving it a go? Admittedly, you have piqued my curiosity and now I will probably have a go.

Cheers.

Jeremy
