  Abstract: In this paper we study the Steiner tree problem over a dynamic set of terminals. We consider the model where we are given an $n$-vertex graph $G=(V,E,w)$ with positive real edge weights, and our goal is to maintain a tree in $G$ which is a good approximation of the minimum Steiner tree spanning a terminal set $S \subseteq V$, which changes over time. The changes applied to the terminal set are either terminal additions (incremental scenario), terminal removals (decremental scenario), or both (fully dynamic scenario). Our task here is twofold. We want to support updates in sublinear $o(n)$ time, and keep the approximation factor of the algorithm as small as possible. #R##N#The Steiner tree problem is one of the core problems in combinatorial optimization. It has been studied in many different settings, starting from classical approximation algorithms, through online and stochastic models, ending with game theoretic approaches. However, almost no progress has been made in the dynamic setting. The reason for this seems to be the lack of tools in both online approximation algorithms and dynamic algorithms. In this paper we develop appropriate methods that contribute to both these areas.
