dito above.. I couldn’t find anything in the NetworkX docs… In Python Igraph, i can just use: Answer Event though I came too late I want to contribute with my proposal, since I was looking for the same answer: I am also looking for a command in the networkx package to find the “sources” and the “targets” of a Directed

Module dependency graph in Python 3
How do I graph module dependencies in Python 3? I found snakefood, but it seems to only work with Python 2. Answer I built a tool based on pydeps here.
BFS algorithm in Python
Guys! Can someone help me with this bfs code? I can’t understand how to solve this queue line. Answer To extend your queue with all nodes not yet seen on the path, use set operations: or use a generator expression: Lists don’t support subtraction. You don’t really need to filter the nodes, however, your code would work with a simple:
How to trace the path in a Breadth-First Search?
How do you trace the path of a Breadth-First Search, such that in the following example: If searching for key 11, return the shortest list connecting 1 to 11. Answer You should have look at http://en.wikipedia.org/wiki/Breadth-first_search first. Below is a quick implementation, in which I used a list of list to represent the queue of paths. This prints: [‘1’, ‘4’,
What scalability issues are associated with NetworkX?
I’m interested in network analysis on large networks with millions of nodes and tens of millions of edges. I want to be able to do things like parse networks from many formats, find connected components, detect communities, and run centrality measures like PageRank. I am attracted to NetworkX because it has a nice api, good documentation, and has been under
Knight’s Tour using a Neural Network
I was looking at the knights tour problem and decided to have a go at implementing it in python using a neural network to find solutions. The general explanation of the method can be found on Wikipedia While I think I have implemented it correctly (I can’t see anything else that is wrong), it doesn’t work, it updates a few
