Webgraph. Reachability queries are of course special cases of (di-rected) distance queries as there is a path from u to v if and only if the distance from u to v is ﬁnite. If we are only interested in reachability properties we may as-sume that the weight of all the edges of the graph is 0. Pathqueries could be answeredusing repeated ﬁrst-edge ... WebSep 1, 2024 · Reachability is often a subquery of many other complex queries, such as graph matching queries.
