Dynamic reachability is a term used in computer science and graph theory to describe the ability to determine whether there is a path between two nodes in a graph that may change over time. This is in contrast to static reachability, which assumes that the graph does not change and the path between nodes is fixed.
Dynamic reachability is important in many applications, such as network routing, database query optimization, and social network analysis. In these applications, the graph can change due to various reasons, such as node failures, new connections, or updates to the data. As a result, algorithms for dynamic reachability need to be able to efficiently update the reachability information as the graph changes.
There are several approaches to dynamic reachability, including incremental algorithms that update the reachability information for specific changes, and fully dynamic algorithms that can handle any type of change in the graph. Some popular algorithms for dynamic reachability include the transitive closure algorithm, the reachability tree algorithm, and the dynamic transitive closure algorithm.
Overall, dynamic reachability is an important problem in computer science that requires efficient algorithms to handle changes in graphs over time.
