报告摘要：The famous Steiner tree packing problem in undirected graphs is not only an important theoretical problem, but also has a strong background in applications. It attracts much attention of researchers in the areas of graph theory, combinatorial optimization and theoretical computer science, and has become an well-established area. It is natural to extend this problem to digraphs, and such problems in digraphs are called directed Steiner type packing problems, including directed Steiner tree packing problem and strong subgraph packing problem. In this talk, we introduce known results on directed Steiner type packing problems and related topics.
