      Werner, Kilian; Garth, Christoph (The Eurographics Association, 2020)
      Topological simplification of merge trees requires a user specified persistence threshold. As this threshold is based on prior domain knowledge and has an unpredictable relation to output size, its use faces challenges in ...
