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
The Set Constraint/CFL Reachability Connection in Practice
Reachability is a fundamental problem that appears in several different contexts: finite- and infinite-state concurrent systems, computational models like cellular automata and Petri nets, program analysis, discrete and continuous systems, time critical systems, hybrid systems, rewriting systems, probabilistic … See more Finite explicit graph The reachability problem in an oriented graph described explicitly is NL-complete. Reingold, in a 2008 article, proved that the reachability problem for a non-oriented graph is in LOGSPACE.
