"Dependency resolution" redirects here. For other uses, see Dependency (disambiguation). In computer science, a topological sort or topological ordering of a directed graph is a linear ordering of its vertices such that for every directed edge (u,v) from vertex u to vertex v, u comes before v in the ordering. For instance, the vertices of the graph may represent tasks to be performed, and the edge
Pre-order (node visited at position red ●): F, B, A, D, C, E, G, I, H;In-order (node visited at position green ●): A, B, C, D, E, F, G, H, I;Post-order (node visited at position blue ●): A, C, E, D, B, H, I, G, F. In depth-first search (DFS), the search tree is deepened as much as possible before going to the next sibling. To traverse binary trees with depth-first search, perform the following ope
Drawing Presentable Trees by Bill Mill When I needed to draw some trees for a project I was doing, I assumed that there would be a classic, easy algorithm for drawing neat trees. What I found instead was much more interesting: not only is tree layout an NP-complete problem1, but there is a long and interesting history behind tree-drawing algorithms. I will use the history of tree drawing algorithm
