列表单极划分问题询问图 G 与列表 L(v)⊆{0,1},v∈V(G) 是否承认映射 f:V(G)→{0,1},使得每个 v∈V(G),f−1(0) 的 f(v)∈L(v) 诱导一个独立集,并且 f−1(1) 诱导 G 中派系的不相交并。这个问题一般是 NP 完全的。我们证明,对于无爪图,该问题可以在 O(n2m) 时间内解决,其中 n 和 m 分别是输入图中的顶点和边的数量。
The list monopolar partition problem asks whether a graph G together with lists L(v)⊆{0,1},v∈V(G) admits a mapping f:V(G)→{0,1} such that f(v)∈L(v) for each v∈V(G),f−1(0) induces an independent set and f−1(1) induces a disjoint union of cliques in G. This problem is NP-complete in general. We show that the problem is solvable in time O(n2m) for claw-free graphs where n and m are the numbers of vertices and edges respectively in the input graph.
