外連通支配集在圖G是一個集合S,使得所有不在S集合的點至少需與S集合裡的一個點相鄰,並且V\S的子圖還是要為連通。在[Computing a minimum outer-connected dominating set for the class of chordal graphs, Information Processing Letters 113 (2013) 552-561] 的論文中,Keil and Pradhan 給了一個線性時間的演算法找最小的外連通支配集在部份的區間圖上,在本篇論文中,我們改善了他們的結果,以線性時間在區間圖上找最小外連通支配集。
An outer-connected dominating set in a graph G = (V,E) is a set S⊆V such that each vertex not in S is adjacent to at least one vertex in S and the subgraph induced by V\S is connected. In [Computing a minimum outer-connected dominating set for the class of chordal graphs, Information Processing Letters 113 (2013) 552-561], Keil and Pradhan gave a linear-time algorithm for finding a minimum outer-connected dominating set in proper interval graphs. In this thesis, we generalize their result to find a minimum outer-connected dominating set in interval graphs in linear time.
