WebThe issue here is with the terminology. You can express reachability in first-order logic; for example you can express it in the language of set theory by quantifying over paths in the graph, and set theory is a first-order theory.. You cannot express reachability in the particular language where the only relations available are the incidence relation on the … WebSep 1, 2024 · Reachability is often a subquery of many other complex queries, such as graph matching queries. A reachability query aims to check the existence of a path between two nodes in a given graph.

WebAug 30, 2024 · Inspired by the optimization of bus/metro/tramway schedules in a public transport network, we consider the problem of turning a collection of walks (called trips) in a directed graph into a temporal graph by assigning a starting time to each trip in order to maximize the reachability among pairs of nodes. WebReachability queries ask whether a vertex can reach another vertex on large directed graphs. It is one of the most fundamental graph operators and has attracted …

WebWhile reachability has been extensively studied on (temporal) unipartite graphs, it remains largely unexplored on temporal bipartite graphs. To fill this research gap, in this paper, we study the reachability problem on temporal bipartite graphs. WebNov 23, 2016 · The graph is potentially cyclic*. Given a list badlist of nodes, I would like to solve a reachability problem: i.e. generate a Map> badmap that represents a mapping from each node N in the list badlist to a set of nodes which includes N or other node that transitively depends on it.
