Graph topological
WebViewed 5k times 18 Ok, so in topological sorting depending on the input data, there's usually multiple correct solutions for which order the graph can be "processed" so that all dependencies come before nodes that are "dependent" on them. However, I'm looking for a slightly different answer: WebA topological index is a numeric quantity of a molecular graph that is mathematically derived. Results: In this paper, we computed a certain degree-based topological indices of threelayered single-walled titania nanosheets and nanotubes. Conclusion: The application of topological indices is vital in quantitative structure-property relationships ...

WebSep 29, 2024 · Scheduling problems — problems that seek to order a sequence of tasks while preserving an order of precedence — can be solved by performing a topological sort on a directed acyclic graph (DAG). WebMay 18, 2011 · This is like finding the longest path for each vertex in the graph. For general graphs this is NP-hard, but since the graph is a DAG, we may use a topological sort to do this in polynomial time. 2 - Compute the indegree of each vertex (that is, count the number of edges entering them).
WebJan 23, 2013 · If you have a specific graph, then you can use the following procedure to compute the number of paths: 1) Topologically sort the vertices. The first vertex in the topological sort must be s 0 and the last one must be e 0 (unless I misunderstand your question; if so, just use the portion of the topological sort between the start and end … 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 ...
