We call this dynamic sum-of-radii clustering problem. We present a data structure that maintains a solution whose cost is within a constant factor of the cost of an optimal solution in metric spaces with bounded doubling dimension and whose worst-case update time is logarithmic in the parameters of the problem."}],"year":"2020","publication_status":"published","oa":1,"quality_controlled":"1","article_type":"original","day":"01","status":"public","citation":{"ista":"Henzinger MH, Leniowski D, Mathieu C. 2020.
