11 Mar 2013	The Bellman-Ford-Moore Shortest Path Algorithm A simple, efficient sparse implementation of the original Bellman-Ford-Moore Shortest Path Algorithm Author: Derek O'Connor	Derek, I sent you an email outlining the real problem data/context etc. I look forward to your reply!
08 Mar 2013	The Bellman-Ford-Moore Shortest Path Algorithm A simple, efficient sparse implementation of the original Bellman-Ford-Moore Shortest Path Algorithm Author: Derek O'Connor	My mistake! Yes I can see you have written it in. Excellent algo that works straight out of the box.

08 May 2013	The Bellman-Ford-Moore Shortest Path Algorithm A simple, efficient sparse implementation of the original Bellman-Ford-Moore Shortest Path Algorithm	Roland	Dear Derek, Do I understand correctly when I say that your function is only capable of computing the shortest path between a root and all other nodes. I am looking for a function that efficiently computes shortest paths between all nodes in a subset of the nodes of the whole graph. Do I understand your code correctly when I say the following: - I would have to call the function multiple times (for each root). It is not possible to specify r as a vector of roots? In other words, this algorithm does not save any info when you have to compute path from multiple roots. - All computation spent on shortest paths to nodes that I do not need is lost. Is this really necessary (i.e. inherent to the Bellman-Ford algorithm) or could this could become faster if it is adapted to the situation I need it for? Thank you very much for your reply. Kind regards. Roland	Comment only

08 Mar 2013	The Bellman-Ford-Moore Shortest Path Algorithm A simple, efficient sparse implementation of the original Bellman-Ford-Moore Shortest Path Algorithm	Derek O'Connor	@none Thanks for your compliments. I would be grateful if you would post or send me your results for these REAL problems. For example, I have not been able to find the official optimum solutions to the problems. This makes me uneasy.
