Find path in graphs

this one helps. You are getting the print out 5 times because you are recursively calling find_path.
See the code:
code :
for vertex in graph[start_vertex]:
    if vertex not in path:
        extended_path = self.find_path(vertex, end_vertex, path) #this is being hit 4 times

Are there any R Packages for Graphs (shortest path, etc.)?

To fix this issue Sure, there's a Task View that gathers a fair number of the graph-related Packages. (The page linked to is a CRAN portal, which uses iframes, so i can't directly link to the Graph Task View. So from the page linked to here, click on Task Views near the top of the LHS column, then click on the Task View gR, near the bottom of the list.
Among the Packages there, igraph, for instance, has graph-theoretic functions such as you have mentioned in your Q.

Graphs: figure out if the path is at least X% better than others

fixed the issue. Will look into that further The only way I see to do this is to remove the edges of the given path from the graph, find a minimum weight path from A to B in the smaller graph, and compare.
To solve this problem using this approach, try one of these well-studied algorithms:

Shortest path(s) in linked graphs

hope this fix your issue I'm not sure about 'prior art' in this domain, but I guess I can think of a 'straightforward solution'.
Find the best path in the Graph 1 (the first graph) separately, as shown in the 'Picture Example'. Compute the cost function for this path, say CF1. Find the number of coloured nodes in Graph 1's optimal path. For all coloured nodes in Graph 1, remove all alternate connection from Graph 2, i.e, ensure that a path in Graph 2 has to go through the coloured nodes used in Graph 1. Find the optimal path in Graph 2 and compute its cost function, say CF2. Compute CF1 + CF2 Repeat steps 1 to 5, but this time start with Graph 2 and then match Graph 1's coloured nodes with Graph 2's initial optimal path.

like below fixes the issue That sounds like an exponential problem because you can arbitrarily add any number of edges between your source and target nodes, and that is for the simplest case where all edges have weight (1).
For purposes of discussion, let's simplify the problem into two sets of graphs, those with all edges having a weight of 1 and another set where all edges have a weight "w" of 2 for a target weighted path "t" of 100.

I wish did fix the issue. You should check out QChart.js:
