I'm dipping my toe in graph theory and found that R has a rich
collection of network and graph tools. However, I can't seem to put my
finger on the solution to my problem. There are several procedures
available in R for finding a shortest path along edges between vertices
based on the cost of traversing a link, but my problem is to find _all_
of the _longest _paths between vertices for a critical path method-type
computation and others in the future. Aside from brute force searching
of all possible paths for the longest and piling up a list of those with
the same length, can someone point me to a method that's already been
figured out? One that I'm trying is to use the inverse of the
traversing costs but my first, naive, test gave me the shortest path
again. Any thoughts?
Regards
David
