Graph reachability review
WebAbstract: Reachability 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 … WebNodes in the exploded graph correspond to pairs, as in "Precise Interprocedural Dataflow Analysis via Graph Reachability" (Thomas Reps, Susan Horwitz and Mooly Sagiv). We reuse nodes for pairs we’ve already seen, and avoid tracking state too closely, so that (hopefully) we rapidly converge on a final exploded ...

WebApr 27, 2024 · Imagine I have given a directed graph and I want a numpy reachability matrix whether a path exists, so R(i,j)=1 if and only if there is a path from i to j; networkx … 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 ...
WebBehavioral analysis considers (i) the initial marking of the Petri net and (ii) its reachability graph. The reachability graph of a Petri net is a directed graph, G = ( V, E ), where each node, v ∈ V, represents a reachable marking and each edge, e ∈ E, represents a transition between two reachable markings.

WebMay 1, 2024 · Reachability preserving compression is a technique that compress a directed graph 1 with respect to a certain class of queries, and only the information related to the query class is retained in the compressed graph. The query evaluation methods on the original graph can be directly applied to the compressed graph without decompression.
