All possible paths from one node to another in a directed tree (igraph) http://stackoverflow.com/questions/3971876/all-possible-paths-from-one-node-to-another-in-a-directed-tree-igraph It is also provided that the graph does not contain any cycles. Due to these two reasons infinite list of paths is impossible... while a DAG's branches can flow together so long as no cycles are introduced. Your solution can be found as find_all_paths..

Does Python GC deal with reference-cycles like this? http://stackoverflow.com/questions/8025888/does-python-gc-deal-with-reference-cycles-like-this Python GC deal with reference cycles like this Using objgraph I found a bunch of objects like this.. like this Will Python's garbage collector deal with cycles like this or will it leak A slightly wider view of the loop.. Python's standard reference counting mechanism cannot free cycles so the structure in your example would leak. The supplemental..
Why does python use both reference counting and mark-and-sweep for gc? http://stackoverflow.com/questions/9062209/why-does-python-use-both-reference-counting-and-mark-and-sweep-for-gc there was no garbage collection for cyclic objects so cycles led to memory leaks.
