The goal of . is to find as many element-disjoint Steiner trees as possible. . is known to be .-hard even for |.|?=?3 [1]. It is also known that . is .-hard to approximate within a factor of Ω(log|.|)

Bazillentr?ger und Dauerausscheiderset of a graph’s vertex set can be extended to a .-colouring of the whole graph. A .-list assignment of a graph is an allocation of a list — a subset of {1,…,.} — to each vertex, and the ... problem asks whether the graph has a .-colouring in which each vertex is coloured with a colour from its list
