While decidability was still … WebJun 13, 2024 · The reachability problems and shortest-path problems have been extensively studied not only for general graphs but also for special classes of graphs; directed planar graphs , Euclidean spanners [9, 19], and disk-intersection graphs [3, 5]. In the following, we introduce several results for transmission graphs of disks in the plane.

The reachability problem for branching vector addition

Webputational complexity of the reachability problem for VAS remains one of the most well-known open questions in theoretical computer science. While decidability was still unknown, Lipton made initial progress on the problem by showing it ExpSpace-hard [12], which is still the highest known lower bound. A few years later, Mayr showed the prob- WebDec 4, 2009 · We consider the problem of reachability and characterise a public (that is, restriction-free) fragment for which it is decidable. This fragment is obtained by removing the open capability and restricting the application of the replication operator to guarded processes only. This decidability result may appear surprising in combination with the ... sly stone top hits https://xavierfarre.com

WebSep 19, 2024 · The new lower bound is a major breakthrough for several reasons. Firstly, it shows that the reachability problem is much harder than the coverability (i.e., state reachability) problem, which is also ubiquitous but has been known to be complete for exponential space since the late 1970s. WebMany problems in static program analysis can be modeled as the context-free language (CFL) reachability problem on directed labeled graphs. The CFL reachability problem can be generally solved in time ( 3), where is the number of vertices in the graph, with some specific cases that can be solved faster. In this
