Hello,
I have defined a directed graph type, and a path type (each variable of type "path" is a sequence (vector) of vertices in the graph such that every two consecutive ones are connected by an edge). Each path is parameterized by arc length.
What I'd like to do is tabulate the function that, for each pair (vertex, path) tells the arc length coordinate of the vertex. I don't want to make it a function: a pair (vertex, path) is likely to come up more than once, and I want to avoid repeating the computation of the arc length coordinate. Just compute it once and store it in a property map.
Where are you storing the paths? Are they attached to vertices? They
don't appear to be from the definitions below. Are you going to be using
all of the
