Reachablity tree
WebFor each statistic, the average number of these reachable vertices is obtained for any random t -ary tree. Keywords: t -ary trees; Reachability; Leaf; Sink; First child. 1. … WebStockmeyer, we show that the reachability problem for vector addition systems with a stack does not have elementary complexity. As a corollary, the same lower bound holds for the satisfiability prob-lem for a two-variable first-order logic on trees in which unbounded data may label only leaf nodes. Whether the two problems are decidable remains

Algorithms for determining reachability fall into two classes: those that require preprocessing and those that do not. If you have only one (or a few) queries to make, it may be more efficient to forgo the use of more complex data structures and compute the reachability of the desired pair directly. This can be … See more In graph theory, reachability refers to the ability to get from one vertex to another within a graph. A vertex $${\displaystyle s}$$ can reach a vertex $${\displaystyle t}$$ (and $${\displaystyle t}$$ is reachable from See more A related problem is to solve reachability queries with some number $${\displaystyle k}$$ of vertex failures.

WebPetri nets are capable of modeling a large variety of systems, properly representing the interactions between the various actions which can occur. The major strength of Petri nets is, of course, in the modeling of systems which may exhibit concurrency; concurrency is modeled in a natural and convenient way.
