19 Feb 2013 K shortest paths in a graph represented by a sparse matrix (Yen's algorithm) Determine the K shortest paths from node S to node T. Author: El-ad David Amir

@El-ad David Amir, I guess, that you're considering the sG sparse graph as being undirected (symmetric), right?
In case of directed graph, then following line should not be used, right
=> k_G( j_next_node, i_node ) = 0; ?

@El-ad David Amir, By symmetric graphs I was referring to undirected graphs ;-)

thx

There is an issue regarding the sampling with this approach. Since the code simply samples the closest value the result is heavily undersampled in some regions (r>>), while it is oversampled in others (r<<).
It would be interesting to have a correct approach that satisfies signal processing criteria (e.g. smooth oversampled regions and grey values where undersampled black and white values come together.
