If you greedily revisit all neighbours which you can improve the longest distance. For example at 9, you can just check that 9+1 > 7 and revisit the 7th node to update it. BUT just to clarify, the big O gets worse.

WebFeb 18, 2024 · Using a directed graph as input, Topological Sort sorts the nodes so that each appears before the one it points to. This algorithm is applied on a DAG (Directed Acyclic Graph) so that each node appears in the ordered array before all other nodes are pointed to it. This algorithm follows some rules repeatedly until the sort is completed. WebApr 10, 2024 · Moreover, by incorporating graph topological features through a graph convolutional network (GCN), the prediction performance can be enhanced by 0.5% in terms of accuracy and 0.9% in terms of AUC ...

WebIn graph theory and theoretical computer science, the longest path problem is the problem of finding a simple path of maximum length in a given graph. A path is called simple if it does not have any repeated vertices; the length of a path may either be measured by its number of edges, or (in weighted graphs) by the sum of the weights of its edges. WebTopological sorting. 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 uv …
