On Selecting Leaves with Disjoint Neighborhoods in Embedded Trees,plane tree . of . leaves, . of which have been .. Each marked leaf is associated with a . (a subtree of .) and any topologically consecutive marked leaves have disjoint neighborhoods. We show how to select in linear time a constant fraction of the marked leaves that have pairwise disjoint neighborhoods.

Mathematisch-physikalische Bibliothekper, we consider the problem of partitioning a graph into a minimum number of induced stars and its decision versions. This problem may be viewed as an amalgamation of the well-known dominating set problem and coloring problem. Although this problem coincides with the dominating set problem on .-fre
