WebApr 6, 2024 · Given a graph G, reachability query can be taken as a specific case of k-hop reachability queries, since they are actually equivalent when \(k \ge \lambda (G)\), where \(\lambda (G)\) represents the length of the longest simple path in graph G. Note that for a general directed graph, we can obtain the corresponding DAG by condensing each ...
WebThe transitive closure of a DAG is the graph with the most edges that has the same reachability relation as the DAG. It has an edge u → v for every pair of vertices ( u , v ) in the reachability relation ≤ of the DAG, and may therefore be thought of as a direct translation of the reachability relation ≤ into graph-theoretic terms. WebThe guard-driven reachability graph (GRG) of WFD-nets is an improved method for analyzing data-flows of concurrent systems. In this experiment, we use DICER 2.0 to compare it with the classical reachability graph (CRG) in terms of state–space and runtime.
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 ...
WebMar 9, 2024 · Relying on the global reachability of the causal graph, this obviously did not affect the semantic relations related to malicious activities. Second, this study used the causality-preserving reduction (CPR) approach , which maintained the ability to perform causal analysis on causal graphs.

In graph-reachability terminology, this amounts to considering all paths rather than considering only the interprocedurally realizable paths. For the IFDS problems, we can bound the extra cost needed to obtain the more precise (realizable-path) answers.
