i've tried , tried; searched , searched, not find algorithm solve problem. want enumerate paths in tree, (not simple paths) start , end leaf nodes (this easy constraint though). for example, tree; 1 / \ 2 3 / \ / \ 4 5 6 7 i want able generate following paths: 4 4-2-5 4-2-5-2-1-3-6 4-2-5-2-1-3-7 4-2-5-2-1-3-6-3-7 4-2-1-3-6 4-2-1-3-7 4-2-1-3-6-3-7 5 5-2-1-3-6 5-2-1-3-7 5-2-1-3-6-3-7 6 6-3-7 7 i guess that's all. i have tried following solution complexity of finding simple paths using depth first search? . however, finds simple paths, therefore paths such 4-2-5-2-1-3-6 not found. are there ways can guide me, algorithm perhaps ? do paths 4-2-1-2-5 count? if so, think have answer: it looks me want each edge visited "once" . take "dual" of graph , @ paths sequence of edges rather sequence of vertices. way, edges become "vertices" , vertices become "edges" . this should reduce problem...
